After hiding unused columns to the right, border on right disappea
 

(Excel 2003) I created a form and only wanted to show the form itself, not
the unused columns and rows.

I selected column J - control-end - column-hide.

The vertical border on the right side disappeared. The only way I was able
to get it to show was to unhide column J - which I'd prefer not to have
showing.

I also tried drawing a rule, but wasn't able to line it up perfectly.

Any suggestions?
