Thank you for the answer, here I need one more option, if I press shift+tab, it should go previous cell as well.

for shift key, evt.shiftKey is true and key code is $.ui.keyCode.TAB for tab key.

I guess you can make the necessary change.

yes it is working,

but here we have requirement like, we have done row grouping. so am getting stuck because group header row is not editable. so once the cursor comes to group header row it will not go further if I click enter button. Can I get the solution for that.

i have attached the Image below group header is mentioned using yellow color, and others cells are particular column is editable. and one requirement like, once it reaches Last row if I press enter it should come first editable cell of that particular column.

you can go past those rows with up / down key

and home key can be used to jump to top row.
