How to add more than 3 columns in editable grid?

Hi,
We are working on 7.3 Version and we have tempo enabled forms.
We have a paging Grid of 3 columns.
And the Issue is we want to add 1 more column which should be editable (In order to feed some data).
We could not accomplish this cause of tempo enabled forms.
Any Help Appreciated.

Thanks in advance.
