This PR provides
FocusTable
with support for handling keyboard tabbing behavior control. Specifically, when a scope is provided as a prop viatabScope
, then theFocusTable
will attempt to automate the control and setting of host component'stabIndex
. This ensures that a single keyboard tab will move to the next browser tab focusable element after the table. Tabbing back into the FocusTable should resume the previously selected cells focus.Under the hood, we proxy the
tabIndex
descriptor of the givenHTMLElement
and track thetabIndex
value so we can correctly reset to the right value (similar to how we trackinput
values). Otherwise we pragmatically control the value to-1
when we don't want a field to be browser tab focusable.
