Additional functionality requested by the customer:

If the table has a horizontal scrollbar, it would be nice if the left/right arrow keys scrolled the table horizontally.

Support for Home/End/PgDown/PgUp would also be nice. For table without a paginator this could scroll the table contents, while for tables with a paginator these keys could cause a page change.

Note that these requirements have been met via work done in ICE-10798. However, the original JIRA request for arrow key support to move the selection highlight is still outstanding.

r521280: added support for highlighting adjacent rows with the up and down arrow keys and for selecting the highlighted row when pressing the space or enter keys, when row selection is enabled

Also, I verified that for tables with a paginator, the home, end, pgup, and pgdn keys already perform their expected functions. For scrollable tables, those keys also scroll the contents as expected.

r52187: fixed issue with keyboard row navigation not working with row expansion (as part of ICE-11380)

Re-opened to backport to the 3.3 maintenance branch.

Review Notes

It would be good if this can be demonstrated in one of the showcase demos.

r52431: added code to automatically give focus to the selected/deselected row or cell, in order to be able to navigate the rows or cells from that point

r52432: added explanation to the ace:dataTable > Selection demo regarding keyboard navigation
