I don't think it is as easy as you do. I understand how to get the
length of the number that is in the cell, but what is more important to
me is that when I toggle the underline it uses enough spaces to take up
95% of the cell. It needs to be consistent so that I can use it just
as easily between cells that are 10 wide or 30 wide. I hope I am
explaining myself correctly.

Thanks
