New row appears when tabbing to second column

[Ryan J Ollos]

I installed and applied the example configuration.

A new row appears when tabbing to the second column:

I think the new row should only appear when pressing tab while in the final column:

I haven't found a way to delete an empty row, and the empty row is rendered:

Alternatively, we could strip off empty rows on submit, though even in that case I would say the new row should not appear until the last column gets focus.

If empty rows are not stripped off on submit, a delete button would be nice.
