DataGrid Keyboard Navigation
Using your keyboard to navigate around an app is crucial to moving fast and being productive.
0.3.6 Infinite Table added keyboard navigation to your favorite React DataGrid component.
Navigating table cells
By default, navigation is enabled for table cells - that means, as soon as the user clicks a cell, it becomes active and from that point on-wards, the user can use arrow keys, page up/down and home/end keys to navigate.
Check out our documentation for keyboard navigation to see more demos and a complete reference guide.
Pro tip: when in cell navigation mode, you can use the
Shift key to navigate horizontally in combination with page up/down and home/end keys.
In the example below, click a table cell and then use arrow keys to see keyboard navigation in action
Another nice feature of keyboard navigation for cells is that you can specify a default active cell - you do so by using
defaultActiveCell=[2,0] - meaning the cell on row 2 and column 0 should be active initially.
Navigating table rows
Besides cell navigation, row navigation is also available. Switch to row navigation mode by specifying
keyboardNavigation="row" - the rest is similar: user clicks a row, which becomes the active row. Using arrow keys, page up/down and home/end works as expected.
Having a default row set as active is also possible, via
defaultActiveRowIndex=2 - this means the row at index
2 should be initially rendered as active.
Controlling active row/cell
Both cell and row navigation can be used as React uncontrolled and controlled behaviors.
The example below demoes controlled cell navigation - initially starting with no active cell, and it updates the active cell as a result to user changes. This means you as a developer are responsible for updating the value when needed, as you no longer wish to leave this update to happen internally in the table. This makes controlled behavior excellent for advanced use-cases when you want to implement custom navigation logic.
Turning off keyboard navigation
Disabling keyboard navigation is done by specifying
keyboardNavigation=false - this ensures the user can no longer interact with the table rows or cells via the keyboard.
There are a number of ways to customise the appearance of the element that highlights the active cell.
The easiest is to override those three CSS variables:
--infinite-active-cell-border-color--r- the red component of the border color
--infinite-active-cell-border-color--g- the green component of the border color
--infinite-active-cell-border-color--b- the blue component of the border color
The initial values for those are 77, 149 and215 respectively, so the border color is
rgb(77, 149, 215).
In addition, the background color of the active cell highlight element is set to the same color as the border color (computed based on the above r, g and b variables), but with an opacity of
0.25, configured via the
--infinite-active-cell-background-alpha CSS variable.
When the table is not focused, the opacity for the background color is set to
0.1, which is the default value of the
--infinite-active-cell-background-alpha--table-unfocused CSS variable.
To summarize, use:
--infinite-active-cell-border-color--bto control border and background color of the active cell highlight element.
