DataTable
The DataTable is a component for building tables which organize information
into rows and columns.
Import
import { DataTable } from '@dynatrace/strato-components-preview/tables';
Use cases
It is important that the data and columns prop passed to the DataTable are
memoized. Use the useMemo hook to make sure the props do not change on each
render cycle.
Please note that the DataTable, which relies on the CSS Grid for its layout,
is currently limited to a maximum of 10,000 columns, including built-in columns.
Exceeding this limit may cause rendering issues in some browsers. This
restriction is based on the limit enforced by Firefox, which applies the
recommendation of the
W3C CSS Grid Layout Module.
Accessors
Accessors specify how to retrieve column data from your data structure. Accessor strings that contain dots allow you to retrieve nested data. If the actual property key contains a dot, you can escape an accessor by enclosing the string in square brackets. It is also possible to specify an accessor function that returns the value you want to extract. See the code below for examples of each.
Text alignment
If no column type is set, text within the cell is left-aligned by default. To
explicitly change the default alignment, use the alignment property in the
column definition.
Define header groups
It is possible to define header groups by providing a nested array of columns
via the columns property in the column definition. Currently, a header group
can only contain columns and not another nested header group.
Define column types
You can assign a predefined type to every column. Values in those columns will
be rendered and sorted according to each type. Available types are text,
date, bit, number, long, currency, log-content, sparkline,
meterbar, markdown and gantt.
By default, columns of type text will automatically detect links and render
them as such. If you want to disable this feature, set the detectLinks prop in
the column config to false. In case you are using a custom cell renderer, a
detectLinks function is available for you to apply.
When setting the column type to log-content, only the first 1000 characters
will be highlighted in order to keep performance optimized for datasets of any
size. Further, log lines will be truncated after 1000 characters. This limit can
be changed via the truncationLimit property in the column config. Note that
any trailing whitespace is removed after truncation.
If the column type is set to date, nanosecond precision is only supported when
the input includes sub-second time information, such as in formats like
HH:mm:ss.sssssssss. This typically includes the ISO 8601 strings with
fractional seconds. In all other cases, the precision is limited to milliseconds
due to the constraints of the JavaScript Date type.
Customize markdown rendering
Use the customComponentMappings config to override the default markdown
rendering behavior.
import { Components } from '@dynatrace/strato-components-preview/core';
const customMappings: Components = {
h2: ({ children }: PropsWithChildren) => (
<i>
<h2>{children}</h2>
</i>
),
};
const columns = [
// ...
{
header: 'Markdown',
accessor: 'markdown',
id: 'markdown',
columnType: 'markdown',
width: 220,
config: { customComponentMappings: customMappings },
},
];
Font style
The DataTable allows for the customization of font styles across the entire
table or within individual columns. This can be achieved by configuring it in
the table variant options or the column definition.
Provide sub-rows
The DataTable component offers the capability to include sub-rows.
-
Enable sub-rows - To activate this functionality, the
subRowsprop must be defined. This prop accepts either a boolean value, which activates the default sub-row view, or an object configuration. -
Provide sub-rows data - Simply define the respective sub-row data by adding the
subRowsproperty to the parent row's data definition. The specified sub-rows must have the same data structure as the parent rows and can be nested over multiple levels.
Use the defaultOpenSubRows prop to specify sub-rows that are already open upon
initial rendering. The onOpenSubRowsChange handler allows you to react to
changes in the currently open sub-rows.
The defaultOpenSubrows/openSubRows expects the id of the row (unless
otherwise specified, this is the array index of the data) along with a boolean
whether or not it's opened. Nested sub-rows are separated with a dot by default,
so '0.0' would be the first row's first sub-row. For details on how to customize
row IDs, reference the control row IDs section.
Configure sub-rows
To further configure sub-rows, you can pass a configuration object to the
subRows prop, using the following options:
-
accessor- Provide a customaccessorfor retrieving the corresponding sub-rows for each row from the data. -
subRowColumnId- Specify the id of the column that the sub-row indicator should be injected to. By default, this is the first visible column. -
disableSubRow- Accepts a function that will evalute whether or not a specific sub-rows trigger in a row should be disabled.
Control sub-rows
To control the state of the open sub-rows, provide the desired rows using the
openSubRows prop along with a handler for the onOpenSubRowsChange callback.
Use the Sparkline chart
It is possible to pass timeseries data to the DataTable and visualize it with
a Sparkline chart. To achieve this, you need to set columnType to
sparkline in the column definition and use the column accessor to point to
the timeseries data that you want to process.
The Sparkline chart in the DataTable can be further configured via the column
definition. You can set its color and variant by adding
config: {color: string, variant: 'line' | 'area' | 'bar'}. The default
configuration of sparkline is
config: {color: 'categorical', variant: 'line', showContextValues: false}.
Use the MeterBarChart
You can visualize numerical data within the DataTable by using
MeterBarCharts. For more information about the MeterBarChart, refer to the
documentation. To render a
MeterBarChart in the table, follow these steps:
- Set
columnTypetometerbarin the column definition - Use the
accessorproperty to specify which value data you want to process.
The MeterBarChart in the DataTable column can be further customized through
the column definition. You can configure its appearance by using the config
prop, which includes the following options:
- color (string): Specifies the color of the
MeterBarChart. - min (number): Sets the minimum value for the
MeterBarChart. - max (number): Sets the maximum value for the
MeterBarChart. - showTooltip (boolean): Controls whether tooltips are displayed.
- thresholds (array of objects
{name: string, value: number, color: string}): Defines threshold values and their associated colors.
MultiMeterBarChart in tables
To add a MultiMeterBarChart to the DataTable, follow the steps in
MeterBarChart in tables and then provide an array of value objects
(value: {name: string, value: number, color: string}) as data, this will
enable DataTable to visualize a MultiMeterBarChart. For more information
about the MultiMeterBarChart, refer to the
documentation.
Again, similar to the MeterBarChart, you can fine-tune the
MultiMeterBarCharts appearance by setting the colorPalette property to
define a color pattern specifically tailored for the MultiMeterBarChart.
When data is provided as value array objects, color and thresholds props in
config are ingored.
Use the Gantt chart
To visualize column data with a Gantt chart, set the columnType to gantt. The
Gantt column definition also accepts a config prop in the format
DataTableGanttColumnConfig, which allows configuration of the following
options:
min: Axis configuration for the minimum value (MinScaleBoundary).max: Axis configuration for the maximum value (MaxScaleBoundary).xAxisType: Whether the axis type isnumericalortime.nameAccessor: String accessor for the segment's name, which is displayed in the tooltip.colorAccessor: String accessor for the segment's color.colorPalette: The palette that contains the segment color mapping.showBackground: Whether gaps between segments should receive a background.tooltipActions: Actions that should be displayed with the default tooltip. The function provides thesegment,rowandparentdata as parameters.tooltip: Custom tooltip implementation. The function provides thesegment,rowandparentdata as parameters.formatter: Formatter options from the@dynatrace-sdk/unitspackage.annotationsHeader: Configuration for displaying anAnnotationsChartin the header above the x-axis. See theGanttAnnotationsHeaderConfigtype for details.
The data for the Gantt chart must contain the Gantt segment data in this format:
{ start: number; end?: number; }. Each row can display one or more Gantt
segments. If multiple segments should be displayed, you can pass an array of
segment data. The segment data can also contain further properties, e.g. for
configuring its color or name, if the corresponding accessor was specified in
the config.
When configuring annotations for the Gantt chart, please note that the data must
be of the same type as the Gantt data (numerical or time). If min is set
to data-min, or max is set to data-max, the values from the annotation
data will also be considered when determining the axis boundaries of the chart.
Enable full width
By default, the DataTable is set to automatically expand and occupy the full
width of its parent element. However, this behavior changes when the table is
placed within a flex container. In such cases, if you wish to ensure that the
table maintains full width, you can include the fullWidth prop when using the
DataTable component.
When this value is not set, it will grow as needed based on the number of columns and their width.
Enable full height
By default, the DataTable grows as needed based on the number of rows. When
placed inside a container, the table's height can be the same as its parent or
smaller depending on how many rows would be visible inside the parent container.
If you wish to ensure that the table always occupies the full height of its
parent element, you can include the fullHeight prop when using the DataTable
component.
Keep in mind that the fullHeight prop should be applied carefully. Setting
fullHeight on the table that is placed inside a container that takes up the
height of the page can lead to serious performance issues. It is therefore
advisable to use the prop in combination with a well-defined container height.
Control column width behavior via column definitions
The DataTable provides multiple ways of controlling the column width behavior.
-
Fixed width in pixels: You can set a fixed width for the column by specifying the exact number of pixels. For example,
width: 100would set the column to be 100 pixels wide. -
Minimum and maximum width constraints: You can specify
minWidthandmaxWidthin the exact number of pixels to set width boundaries for a column.maxWidthwill not work on fraction widths, to avoid circular width calculations. -
Flexible width in fractions: You can set a flexible width for the column using a fractional unit. This is done by specifying the width as a fraction, like
width: '1fr'. This approach allows the column to take up a proportion of the available space, adjusting dynamically based on the total space available and the fractional values assigned to other columns. For instance, if you have two columns and set their widths towidth: '1fr'andwidth: '2fr', the second column will be twice as wide as the first one. -
Fit to content: To make a column's width automatically adjust to fit the content of its cells, set the column's
widthproperty tocontent. -
Shared leftover space: If you want certain columns to share the leftover space among themselves set the option to a fraction value for those columns. See the example in allow certain columns to occupy the remaining space
-
autowill hand over control about the column size to the browsers grid layout and follows the layout engine and specification of the browser. Reference MDN grid documentation for details. -
You can also set a maximum width for the column when using either of the previous two options by configuring it like this:
{type: 'auto' | 'content', maxWidth: 100}. Here,maxWidthspecifies the maximum width in pixels.
Allow certain columns to occupy the remaining space
You will certainly have some columns in you DataTable that are more important
than others. Between these columns, you can spread the remaining space within
the table by providing a fraction width like 1fr for the columns. In the
example below the columns Memory Total and Timestamp occupy each one
fraction of the remaining space, and the Price column takes up two fractions.
Column sizing
To establish default column widths for the table, you can utilize the
defaultColumnSizing as a DataTable prop. This property requires an object
that maps column IDs to their respective widths in pixels.
Control column sizing
To activate the column resizing feature in DataTable, you need to include the
resizable property within the table’s configuration. This property acts as a
flag that, allows the columns within the table to be adjusted in width
interactively by the user.
You can track the changes in column widths during resizing events by utilizing
the onColumnSizingChange and columnSizing properties. The callback triggered
upon resizing delivers data regarding the current widths of all columns. This
information can be leveraged to record and maintain the dimensions of resized
columns. For instance, as demonstrated here, whenever the email column is
resized, it will revert to a default width of 300px.
As soon as a resizing event starts, all columns that have a fraction width or no width defined will be locked to their current width.
Customize visual representation
The variant prop allows you to customize the appearance of the DataTable by
setting the configuration options available in DataTableProps['variant'].
Row density
The rowDensity option adds spacing around the content within a row. By
default, rowDensity is set to default, which represents a medium spacing. If
the option is set to condensed, the spacing becomes minimal while
comfortable represents the maximum spacing.
Row separation
The rowSeparation option determines how rows should be separated visually. By
default, rowSeparation is set to horizontalDividers which adds lines between
the rows. zebraStripes additionally provides alternate row coloring. By
setting rowSeparation to none, the rows are not separated visually.
Vertical dividers
The verticalDividers option determines whether columns should be separated
visually. By default, false is set which does not separate the columns within
a DataTable. If verticalDividers is set to true, lines are added between
the columns.
Contained
The contained option provides a border for the DataTable. By default,
contained is set to true to display the border. If false is set, no border
is added.
Hidden headers
You can customize the DataTable's appearance to hide the entire header, by
setting headers: 'hidden'.
If you choose to hide the header, please note that the ability to sort columns by header, as well as any actions that could be triggered with column headers, won't be available.
Vertical alignment
Use the verticalAlignment option to configure the vertical alignment of the
cell content. The alignment options are top, center, and bottom. It is
also possible to configure the vertical alignment for header and body cells
separately. By default, all cell content is top-aligned.
Customize cell rendering
To customize the cell rendering, pass the corresponding function to the cell
prop in the column definition. If you want to maintain default cell styling, you
need to wrap each return statement with DataTable.DefaultCell element. Also,
DataTable.DefaultCell supports className and style props, allowing further
customization of the cell appearance.
Within the function passed to the cell property, you can access the cell's
value, rowIndex, rowData and rowId. Additionally, the isLineWrapped
prop provides the current line wrap state of the column in which the cell is
rendered.
Moreover, a format, a formatLogContent and a detectLinks function are
available:
format- Allows you to apply theformatteroptions that have been configured for that cell (either via the column definition or via the columnType).formatLogContent- Formats the given text as a log output.detectLinks- Automatically detects links in the given text and renders them as such using theExternalLinkcomponent.
Customize column header
To customize the column header, simply utilize the header property within the
column definition. Assign a function to this property that returns a customized
JSX element. You can also utilize the optional label property when using a
custom column header, which will be used, e.g., for accessibility and in
elements like the column settings modal. If the label is not defined, the
column's id will be used as a fallback. Similar to cell, if you want to
maintain default header styling, you need to wrap each return statement with
DataTable.DefaultCell element. Also, DataTable.DefaultCell supports
className and style props, allowing further customization of the header
appearance.
Caution: Avoid placing interactive elements within a custom-rendered header if column actions are already configured for the same column. Since a column header with column actions already includes a button element, adding additional interactive elements inside may result in unexpected behavior.
Enable line wrap
The DataTable component offers flexible options for managing the line wrapping
of cell content within your table. Here’s how you can control it:
-
Global line wrapping configuration - To activate line wrapping across all columns, set the
defaultLineWraporlineWrapproperty to true. -
Column-Specific line wrapping - If you prefer to enable or disable line wrapping for certain columns, pass an object to the
defaultLineWrapproperty. Use column IDs as keys and set their values to true (to enable) or false (to disable). -
User-Controlled Line Wrapping - Toggle via column actions: Incorporate
TableActionsMenu.LineWrapinto your table to allow users to switch line wrapping on or off for specific columns through the column actions menu. -
User-Controlled Line Wrapping (entire table) - Toggle via a
DataTable.Toolbaraction: IncorporateDataTable.LineWrapinto you tablesDataTable.Toolbarcomponent to allow users to switch line wrapping on or off for all columns.
Props for Line Wrapping Control
The DataTable also provides properties to manage line wrapping state:
defaultLineWrap- Defines the initial state of line wrapping when the table loads.lineWrap- Sets the line wrapping state.onLineWrapChange- A callback function that triggers when the line wrapping state changes.
The DataTable uses column virtualization to optimize performance. With line
wrap enabled, row heights might change while scrolling horizontally as wrapped
content becomes visible.
Enable sorting
By using the sortable flag, you can enable sorting for the entire table.
Additionally, you have the option to disable sorting on a per-column basis by
configuring the disableSorting property in the column definition. For
meterbar columns, sorting is disabled by default and
can be enabled explicitly by setting disableSorting to false. Please note
that sorting is not supported for
MultiMeterBarCharts.
By default, the first sorting direction is ascending. If you want to change
that, you can configure the sortDescFirst flag for the individual column.
There is also a possibility to invert the sorting logic. Setting sortInverted
to true means the underlying sorting direction will be inverted, but the UI
will not change. This could be useful, for example, when a lower score is
better. Values like null and undefined will be sorted with lower priority
and will always appear at the end of the list.
Columns can be sorted by clicking directly on the header, even on header cells with column actions defined. Sorting indicators and column action indicators are shown on hover or on sorted columns, which allow for header cells to be less cluttered, allowing to focus on the header's content
Sorting programmatically
Control sorting programmatically by setting the sortBy prop, passing an array
with column IDs and sorting directions. Use the onSortByChange callback to
monitor and manipulate sorting changes within the DataTable. If you want to
sort your data before it is passed to the table, you need to disable built-in
sorting by setting sortable={{ manualSorting: true }}. This is particularly
useful for server-side sorting. To initially sort tables without controlling
their state, use defaultSortBy.
Define a sortAccessor
In case the value that should be used for sorting differs from the one returned
by the accessor, it is possible to define a custom sortAccessor in the column
definition. For example, if the accessor returns an object, the sortAccessor may
return a number or string field within the object.
Define a custom sortType
You can specify a sortType in the column definition to control sorting
behavior more precisely. The built-in options are
'text' | 'textCaseSensitive' | 'number' | 'datetime'. However, for more
advanced scenarios, you can pass a function as well. This is particularly useful
for compound data, where a column displays multiple or combined data entries.
When using a custom sortType function, you may also need to define a custom
sortAccessor in your column definition. For details, see:
Define a sortAccessor.
In the example below, a column displays both CPU usage (as a percentage) and memory usage (in GB). The custom sorting function prioritizes higher CPU usage and resolves ties by considering higher memory usage.
Enable pagination
To enable pagination add the DataTable.Pagination component to your table.
This component allows you to configure the default page size and the default
page index via the defaultPageSize and defaultPageIndex props.
Change page size options
The default page size options are 10, 20, 50, 100, 250, 500 and 1000. To
customize these options, use the pageSizeOptions prop, which allows you to
pass the desired page sizes as an array. Please ensure that the passed (default)
page size aligns with the defined options. The table will not sanitize page
sizes that do not exist in the options.
Control pagination
It is also possible to control the page size and the page index using the
pageSize and the pageIndex props together with the onPageSizeChange and
the onPageIndexChange callbacks.
Use server-side pagination
In addition to the regular client-side pagination, it is also possible to use
server-side pagination. For server-side pagination, pass the data for the
respective page to the table and update the enablePrevPage and
enableNextPage flags accordingly. Upon navigating to another page or changing
the page size the corresponding callbacks as well as the onPageChange
callbacks provide the updated values, allowing you to retrieve the corresponding
data.
By default, the server-side pagination does not display the indicator for which
page out of the total number of pages is currently shown, i.e. "Page 1 of 30",
in the bottom right corner. This is because the total number of rows is unknown
since only the data for the respective page is passed. However, adding the
totalRowsCount prop enables this information to be displayed as well.
Enable row selection
To activate row selection in DataTable, you must configure the
selectableRows prop on the table. Assigning a boolean value to this prop will
generate a checkbox in the first column across all rows, enabling selection
functionality. Alternatively, selectableRows can be defined as an object,
allowing for further customization through the following options:
-
disableRowSelection- Accepts a function that takes the row's data as input and returns a boolean value. If it returnstrue, the row will be non-selectable; iffalse, the row will be selectable. -
selectAllBehavior- A string value that specifies whether the ‘Select All’ action applies to only the currently visible rows on the page or to all rows within the table. -
limit- A positive integer that sets the maximum number of selectable rows.
If a limit is specified, rows will still be de-selectable even when
disableRowSelection is enabled. This prevents inconsistent states where the
selection limit is reached but all selected rows are disabled, making it
impossible to adjust the selection.
To set up rows that should be selected as soon as your table loads, you need to
use a prop defaultSelectedRows. This option should be assigned an object that
specifies which rows are selected. Each row is identified by its id, and the
selection state is indicated by a boolean value (true for selected, false
for not selected). To ensure correct selection behavior when updating table data
dynamically (e.g., adding or removing rows), make sure to provide
unique row IDs.
It is possible to select or deselect multiple rows at once by first clicking on
a start row, then holding the Shift key while clicking on an end row.
Control row selection
When you want to control which rows are selected, you use the selectedRows
prop. This prop allows you to specify which rows should be considered ‘selected’
at any given time. To make this dynamic, so that it can change in response to
user actions, you also provide a handler function for the onRowSelectionChange
callback.
Here’s how it works:
selectedRowsprop: This is where you pass an object that represents the currently selected rows. Each row is identified by its id, and the selection state is indicated by a boolean value (true for selected, false for not selected).onRowSelectionChangecallback: This function is called whenever the selection changes, such as when a user clicks on a row checkbox. The callback function receives information about the new set of selected rows. By using these two together, you can maintain the selection state outside of the component, giving you full control over the behavior of the selection.
Control select-all behavior
As previously mentioned, selectAllBehavior is a string value that specifies
whether the ‘Select All’ action applies only to the currently visible rows on
the page or to all rows within the table. Here is an example of doing that and
it's important to note that, as usual, you need to memoize the configuration
object to ensure there are no unwanted side effects.
Enable interactive rows
To activate interactive rows in DataTable, you must configure the
interactiveRows prop on the table. This will make the entire row highlightable
and selectable by the user. A row can be activated either by clicking on it or
focusing it.
Disable auto-activation for interactive rows
By default, interactive rows are automatically activated when they are focused
using the keyboard. However, if you want to disable automatic activation, you
can do so by setting interactiveRows={{ autoActivate: false }}. This allows
you to activate a specific row by pressing the Enter key.
Configure links for interactive rows
To enable navigation from interactive rows, use the link prop within the
interactiveRows prop. link accepts a function that receives the row's data
and returns a URL. When a row is clicked or activated via the Enter key, the
user will be directed to the specified URL.
Control interactive rows
When you want to control which row is currently activated, you use the
activeRow prop. This prop allows you to specify which row should be marked as
active at any given time. To make this dynamic, you can also provide a handler
function for the onActiveRowChange callback. The rows themselves are
identified by their rowId, which can be customized as well. For details on how
to do this, reference the control row IDs section.
In addition to the interactiveRows prop, it is advised to debounce the row
activation when auto-activation is enabled. This allows you to specify by how
many milliseconds the activation of a row should be delayed for better
performance. By default, the row is immediately activated.
Control row IDs
Features like row selection, sub-rows and row interactivity by default use a row
id based on the index of the data that is passed. This can be problematic when
you want to persist any of the states while the data itself changes. For this
usecase you are able to change how rows are identified by providing a rowId
function on the DataTable. When providing a custom row id function, for sub
row identification, the row IDs will be separated by ↳ character.
Enable expandable rows
Expandable rows allow you to add additional data to a row. This information is only visible when the row is expanded.
The default state of each row can be controlled using the defaultExpandedRows
prop on the DataTable.ExpandableRow slot child. To control each row over the
lifetime of the table use the expandedRows property and the
onExpandedRowsChange callback.
In this example, every second row is disabled for demo purposes.
Loading state
Use the loading prop to display a loading indicator. This can be used for the
initial load where columns and data are not yet available, when waiting for data
to be fetched or when performing actions such as moving to the next page. The
loading indicator will adjust accordingly depending on whether columns and data
are already loaded.
Initial table load
Load data
Customize empty state
The DataTable.EmptyState component allows you to configure a custom empty
state that will be displayed if no data or no columns are available.
Configure selected rows actions
The DataTable.SelectedRowsActions component provides an additional slot where
you can perform actions on one or more selected rows in the DataTable
simultaneously. Actions passed to this slot are placed right above the table
header and are shown only when at least one row is selected. If table actions
exist, they are hidden when the selected rows actions menu is active.
Configure table actions
The DataTable.TableActions component provides an additional slot where you can
place custom actions that affect the entire table. Actions passed to this slot
are placed right above the table header.
Configure column actions
The column actions are represented by a button in a column header that opens a drop-down menu. Within the menu, you can include various functionalities allowing end users to perform actions related to the column of the table.
The drop-down menu also appears on right-click, providing additional access to defined cell or column actions. This feature adds a layer of functionality, allowing users to access more options directly from the table.
To configure column actions you need to define the DataTable.ColumnActions
slot component.
Within the DataTable.ColumnActions tag, a function is placed. This function is
designed to receive the current column’s details, enabling the customization of
actions for that column. The function should return a TableActionsMenu object,
which defines the user actions for the cell. It should also include the
TableActionsMenu.Item slot component to represent a single action item,
similar to the TableActionsMenu.Link component that renders a defined link
element as a menu action item. You can assign an onSelect event as a property
of this component, which will execute the specified action upon user
interaction. Additionally, the TableActionsMenu.ItemIcon property can be
applied to the item to incorporate an icon for the action trigger element. For
cross-app navigation, the TableActionsMenu.Intent slot component can be used
to define an intent item. See the Configure intents
section to learn more about the configuration of intents in the DataTable.
To enable users to copy column values to the clipboard, you can use the
predefined TableActionsMenu.CopyItem slot component. To semantically group
items within the menu, use TableActionsMenu.Group and
TableActionsMenu.Label. For more information about menu groups and labels,
refer to the documentation. The user action
menu supports multi-level menus, allowing you to configure sub-menus using the
slots TableActionsMenu.SubMenu, TableActionsMenu.SubContent, and
TableActionsMenu.SubTrigger.
To configure actions for a particular column its ID must be provided to the
column property. If default actions should be available for all columns that
do not explicitly have actions configured, the DataTable.ColumnActions column
ID is omitted.
Configure cell actions
The cell actions are represented by a button in a table cell that opens a drop-down menu. Within the menu, you can include various functionalities allowing end users to perform actions related to the cell of the table.
The cells within the DataTable allow custom interactive elements, allowing you
to include links or other actionable elements within cells with cell actions
defined.
To configure cell actions you need to define the DataTable.CellActions slot
component. Within the DataTable.CellActions tag, a function is placed. The
function should return a TableActionsMenu object, which defines the user
actions for the cell. It should also include the TableActionsMenu.Item slot
component to represent a single action item, similar to the
TableActionsMenu.Link component that renders a defined link element as a menu
action item. You can assign an onSelect event as a property of this component,
which will execute the specified action upon user interaction. Additionally, the
TableActionsMenu.ItemIcon property can be applied to the item to incorporate
an icon for the action trigger element. For cross-app navigation, the
TableActionsMenu.Intent slot component can be used to define an intent item.
See the Configure intents section to learn more about the
configuration of intents in the DataTable.
To enable users to copy cell values to the clipboard, you can use the predefined
TableActionsMenu.CopyItem slot component. To semantically group items within
the menu, use TableActionsMenu.Group and TableActionsMenu.Label. For more
information about menu groups and labels, refer to the
documentation. The user action menu supports
multi-level menus, allowing you to configure sub-menus using the slots
TableActionsMenu.SubMenu, TableActionsMenu.SubContent, and
TableActionsMenu.SubTrigger.
To assign actions to the cells in a specific column, you need to specify the
unique identifier (ID) of the column. This ID is then used as the value for the
column property within the DataTable.CellActions configuration. This tells
the DataTable which column the actions should be associated with. If default
actions should be available for all columns that do not explicitly have actions
configured, the column ID is omitted.
Configure row actions
Configuring row actions in a DataTable involves adding an action column to the
far right of the table. This column should contain buttons, menus, or links that
allow users to perform actions specific to each row.
To set up row actions in the table you need to locate DataTable.RowActions
slot component as a DataTable child. This component takes a function that
receives the current row’s data as well as some meta information about the
tables layout as its parameters. This allows you to access and manipulate the
data for that specific row. The function needs to return a ReactNode that
defines the user actions for the row. Most likely you want to add some primary
actions as buttons and secondary actions into a menu.
Configure column visibility
The column visibility feature allows you to specify which columns should be
visible and which should be hidden. Use the defaultColumnVisibility prop to
define the column visibility state. Provide an object with the respective column
IDs as keys and boolean values indicating their visibility. A value of true
means the column is visible, while false means it is hidden. By default, all
columns are visible.
Column visibility UI elements
To allow the user to show and hide columns, you need to configure the
corresponding UI elements in the table. Column visibility can be controlled
through either the DataTable.Toolbar or the DataTable.ColumnActions.
Use the DataTable.VisibilitySettings component inside the toolbar, to render a
trigger for the column settings overlay and enable the visibility settings. To
enable users to hide a column via the column actions, include the
TableActionsMenu.HideColumn as a menu item.
To prevent a specific column from being hidden, set the disableColumnHiding
prop to true in that column's definition. For header groups, the group itself
cannot be hidden if at least one of its child columns has disableColumnHiding
prop set to true.
Control column visibility
To control column visibility, use the columnVisibility prop to provide the
visibility state, along with the onColumnVisibilityChange callback which
allows you to react to visibility changes.
Column visibility reset
Column visibility can be reset to default original value using the column
settings overlay trigger in toolbar. A custom reset state can be set using the
resetColumnVisibility prop in DataTable.VisibilitySettings component, which
allows the column visibility state to be set to the provided reset state. In
uncontrolled, the column visibility resets to defaultColumnVisibility prop
state if present or original visibility state. This ensures that the columns can
be easily reverted to their default visibility state whenever needed. Reset
button is disabled when the current state is the same as the default state.
Customize the label of the column settings trigger
Adding the DataTable.ColumnSettingsTrigger component inside
DataTable.Toolbar in combination with DataTable.VisibilitySettings,
DataTable.ColumnOrderSettings, or DataTable.ColumnPinningSettings allows you
to configure a custom text that will be displayed as the label of the trigger
for the column settings overlay.
Open column settings programmatically
You can open the column settings programmatically using the
openColumnSettings() function. By default, the settings modal is opened with
the same options (column visibility, column order and/or column pinning
settings) as specified in the DataTable.Toolbar. However, you can override
these options via the function's parameters. This is particularly useful if the
data table is used without its built-in toolbar.
Configure column order
To enable column ordering, set the columnOrdering prop to true.
For uncontrolled, you can optionally use defaultColumnOrder to define the
initial column order, by providing an array of all column IDs in the desired
order. If you don't specify any order, the initial order is inferred from the
column definition.
The defined column order should include all columns and ensure that child columns with the same parent are not separated. To avoid invalid configurations, the passed column order is validated and corrected if necessary. The following issues will be resolved:
- duplicate column IDs
- column IDs that don't exist in the column definition
- missing column IDs
- column IDs within the same group that are not adjacent
When column ordering is enabled, column headers will be draggable. To move a column to another position hold down the mouse on the column header and then release it when you have moved it to its destination. This is also possible using touch (press, hold and release).
Column order UI elements
In addition to drag and drop, the column order can be adjusted using
corresponding UI elements in the table. You can control the column order through
either the DataTable.Toolbar or the DataTable.ColumnActions.
Use the DataTable.ColumnOrderSettings component within the toolbar to render a
trigger for the column settings overlay and enable the column order settings. To
allow users to move a column via the column actions, include the
TableActionsMenu.ColumnOrder as a menu item.
Control column order
To control column order, use the columnOrder prop to provide the desired
order, along with the onColumnOrderChange callback which allows you to react
to changes in the column order.
Reset column order
Column order can be reset to default original value using column settings
overlay trigger inside the toolbar. A custom reset state can be set using the
resetColumnOrder prop can be set in DataTable.ColumnOrderSettings component,
which allows the column order state to be set to the provided reset state. In
uncontrolled, the column order resets to defaultColumnOrder prop value if
present or original order. This ensures that the columns can be easily reverted
to their default order whenever needed. Reset button is disabled when the
current state is the same as the default state.
Configure row order
To enable row ordering, set the rowOrdering prop to true. Note that if you
are providing your own row IDs you need to specify the rowId prop.
For uncontrolled, you can optionally use defaultRowOrder to define the initial
row order, by providing an array of all row IDs in the desired order. If you
don't specify any order, the initial order is inferred from the order in data.
To enable drag and drop row ordering, you can pass a configuration object to the
rowOrdering prop with the option enableDragAndDrop set to true.
Additionally, the option disableRowDragAndDrop accepts a function that takes
the row's data as input and returns a boolean value. If true is returned, drag
and drop will be disabled for the row, otherwise it is enabled.
Additionally, the lockDisabledRows option ensures that rows with disabled drag
and drop remain fixed in place when sorted to the start or end of the table.
Consequently, other rows cannot be dropped above or below these locked rows. If
set to true, the rows are locked when sorted to the start or end of the table.
Optionally, lockDisabledRows can be set to 'start' or 'end' if rows should
be locked solely at the start or at the end.
When drag and drop is enabled, a drag handle for every row will be rendered in the first column. To move a row to another position hold down the mouse on the drag handle and then release it when you have moved it to its destination. This is also possible using touch (press, hold and release).
Alternatively, using the keyboard use the tab key to focus the drag handle and then press the spacebar once. Use the up and down arrow keys to move the row to its destination and then press the spacebar again to release it. To cancel press escape.
If you are using row ordering with pagination and modifying the data, you
should set autoResetPageIndex to false to prevent the pagination jumping
back to the first page. If you are only modifying the rowOrder then there is
no need.
Control row ordering
For controlled, the rowOrder prop holds the order of the rows. This is an
ordered set of string IDs of the rows. For controlled, it's up to you to use the
onRowOrderChange event to update row order and optionally update the original
data as you see fit.
Order rows with disabled drag and drop
To facilitate disabling of drag and drop functionality for certain rows, we
provide the useLockedRowOrder hook. This hook disables drag and drop
functionality for the specified rows and locks them at the start or the end of
the table. It takes an object with the following options:
initialRowOrder- An ordered set of row IDs representing the initial row order.lockedRows- A set of row IDs for which drag and drop is disabled and should be sorted.position- The position where the rows with disabled drag and drop should be grouped. Use'start'to position the rows at the start of the table and'end'to group them at the end. By default, the rows are positioned at the start.
Configure pinned columns
Column pinning enables individual columns to remain pinned to the left or right
edge of the table, improving visibility for important data. To enable column
pinning, set the columnPinning prop to true.
The built-in columns for drag and drop row ordering, row selection, expandable rows, and row actions are always pinned by default and cannot be unpinned, regardless of whether column pinning is enabled.
For uncontrolled usage, you can use defaultPinnedColumns to define the initial
pinned state. This prop accepts an object with two optional properties:
left: An array of child column IDs to pin to the left side.right: An array of child column IDs to pin to the right side.
While ordering is supported for unpinned columns, pinned columns cannot be re-ordered. Unpinned columns can be re-ordered via column actions and the column settings modal.
Column pinning UI elements
Column pinning can be configured through the table’s UI. To enable users to pin
and unpin columns via the column actions menu, use DataTable.ColumnActions and
include TableActionsMenu.ColumnPinning as a menu item.
To render a trigger for the column settings overlay and enable column pinning
settings, use the DataTable.ColumnPinningSettings component inside the
DataTable.Toolbar.
Control column pinning
To control column pinning, use the pinnedColumns prop to specify which columns
should be pinned to the left or right. To handle updates, provide an
onPinnedColumnsChange callback to respond to changes in the pinned column
state.
Highlight cells
Cells can be highlighted in different colors depending on the specified
threshold. In the column definition, you can configure the threshold for every
column. You can specify value, comparator, color, backgroundColor, and
accessor. The color will be applied to the cell text and backgroundColor
to the cell background. The accessor prop can also be used for providing
custom accessor for the cell value that can be used for threshold calculations.
If the column cell value passed is a string (text), the threshold comparator can
be set with either an equal-to or not-equal-to operator. On the other hand,
if your value is a number, you can utilize one of the following operators:
greater-thanless-thangreater-than-or-equal-toless-than-or-equal-toequal-tonot-equal-to
If the value of the cell is an object, the threshold accessor could return
a specific attribute within the object, such as a number or string. This
allows for more complex threshold calculations based on specific attributes of
object values.
When multiple thresholds are applicable (evaluate to true) the final valid threshold has priority. Also, if both row and column thresholds apply to a cell, the column threshold takes precedence over the row threshold.
Highlight rows
You have the option to highlight an entire row. The thresholds for row
highlighting can be configured at the table level using the rowThresholds
prop. This prop accepts the same options as the cell threshold with the addition
of a type. However, it also allows you to specify which cell value should be
used for the row threshold by defining an accessor or id.
You can add either a single rule or multiple rules to the threshold definition. If you choose to use multiple rules, you can define different thresholds for different cell values within a row. However, regardless of which threshold is met, the same color will be applied to the entire row.
The type determines how the highlighted row will be visually marked. The
pill type accepts a color and shows a marker on the start of the row. The
hightlight type accepts color and backgroundColor and changes the
textcolor and background color of all cells in a row.
Define custom comparator
You can define a custom comparator function to evaluate the threshold using
your own logic. This function should return a boolean. If it returns true,
the threshold is applied; if false, it's not. The function receives the row
data as input. Please note that this custom comparator function will not be
serialized for sharing via intents.
Download data
The DataTable.Toolbar has an item DownloadData which enables the downloading
of the table data. Depending on your table configuration, you can choose between
downloading all data, downloading the current page and only downloading the
selected rows. Only visible columns are considered.
CSV data is generated in the browser. For very large tables (with many rows or large cell content), exporting all rows may slow down the browser or even cause it to crash. In such cases, prefer exporting only individual pages or selected rows.
If the table has sub-rows, an additional column index is
added to the downloaded table data, indicating the row's indentation level. For
example, the first row has index 1, its first sub-row has index 1.1 and so
on. Sub-rows are included in the downloaded table data regardless of whether
they are currently open or closed. When downloading the current page, all
sub-rows of the rows on that page are included, even if some sub-rows are
actually rendered on following pages.
When downloading, double quotes are escaped and if the text has commas, new
lines, double quotes, tabs or carriage returns, the entire line is enclosed in
double quotes. In addition, values starting with =, +, -, @, \t and
\r are escaped with a single quote to mitigate CSV injection. Also note that
if you have custom cells you can provide a toString function on the data
object for customized download output.
The DataTable also provides the onDownloadData callback that fires once data
has been downloaded. The callback's subset parameter indicates whether all
data, the current page, or the selected rows were downloaded.
The preferred way is to use the toolbar item as above but if you have some good
reason not to use the toolbar you can create your own download trigger which
programmatically calls downloadData() with one of the parameters 'all',
'page', or 'selected'. See the following example.
Configure intents in the toolbar
The DataTable.Toolbar accepts DataTable.Intent slot components, offering a
menu with the specified intents for cross-app navigation. See the
Configure intents section to learn more about the
configuration of intents in the DataTable.
Format cell data
You can format the cell data via the column definition, by specifying the column
property formatter. For configuration, use the corresponding options from
'@dynatrace-sdk/units', i.e. FormatOptions for numbers, FormatDateOptions
for dates, and DataTableCellFormatterCurrencyOptions for currencies.
Export Config
The DataTable's configuration can be exported at any time for various
purposes, such as sharing the configuration with other applications
through an intent. The current configuration
can be retrieved by creating and assigning a ref to the corresponding ref
property of the DataTable, and then calling ref.getConfig() function.
When the getConfig function is invoked, a snapshot of the serialized
configuration is returned. As such, it will not change if the DataTable's
configuration is subsequently modified. It is recommended to ensure that you
apply all your required configurations to the DataTable before calling this
function.
Import Config
The configuration provider for the DataTable accepts a JSON object and also
accepts a string as input for importing a serialized configuration. When a
string is provided, it is internally parsed and applied as the DataTable
configuration.
If the configuration provided does not match the properties of the DataTable
configuration, any unknown properties will be ignored. Additionally, if required
properties are not provided, or the given config is invalid, default values will
be applied.
We do not support dynamically changing default values, as doing so goes against
their intended purpose. Therefore, changing the values of defaultPageSize or
defaultPageIndex in the configuration for pagination will not update the
corresponding props in the DataTable. If you need to set default values, it is
recommended to ensure that you always do that before importing the
configuration.
Due to potential version mismatches in DataTable packages used in different
applications, importing a configuration from another application may produce an
unintended outcome and not result in a perfect match.
Scroll to a given row
The DataTableRef provides the scrollToRow method, which enables programmatic
scrolling to a specific row in the table, identified by its rowId.
If the target row is a sub-row, the parent row must be expanded beforehand. Otherwise, the sub-row will not be accessible for scrolling.
Configure intents
An intent is a message object that enables users to pass the user flow from one app to another. It is possible to perform actions such as viewing data in another application. You can read more about intents in the Intents docs.
The DataTable supports intents within the following slot components:
DataTable.CellActionsandDataTable.ColumnActions: Use theTableActionsMenu.Intentslot within theTableActionsMenu. For custom icons, utilize theTableActionsMenu.ItemIconslot withinTableActionsMenu.Intent.DataTable.RowActions: Provide aMenucomponent containing theMenu.Intentslot. For custom icons, place theMenu.ItemIconslot withinMenu.Intent.DataTable.Toolbar: Use theDataTable.Intentslot to configure intents. Optionally, set a custom icon by passing the desired icon to theiconprop.
Intents can be configured using the following options:
payload: An object containing the data to be passed to the target app. The structure depends on the target application's requirements.options: Configuration options for the intent.keyProperties: Array of properties that should be included as keys in the intent.recommendedAppId: ID of the application that will be launched to handle the intent.recommendedIntentId: ID of the action that is passed to the application.responseProperties: Array of properties to be included in the response.
onResponse: Optional callback function that is called when a response is received from the target app.
