Allow Tab key in order to go out from the DataSheet to focus other DOM elements

[vivaslj1]

is there any way to press tab-key when last cell is focused (last-row / last-column) to change focus on the next element of the dom?, maybe modifiying cell-renderer?

Default behaviour in a web is press tab-key in order to change focused element, but when click on datasheet, i can not move with tabkey anywhere unless i click on other dom element.

Any help greatly received!
