Table Cell Editing via Tabbing

It would be nice if there was an option on editable table cells to allow rapid entry of values when tabbing through the cells. It seems that when tabbing to a cell to edit the contents that if the existing value is not deleted or selected with a mouse, any new value entry gets appended to the existing value.

Maybe there is a way to do this that I’m missing?


an excel-like tabbing would be great!
I had the same thoughts about my table interfaces.
