Inserting column in Table. Should I be using subforms?



Hi -

Attached is a document I have been working on with many tables throughout the form.  I need to add an additional column added to almost all of the tables.

I have tried to use the insert column function, but I can't get it to work.  I shrank up the tables to see if I needed more space, but it still didn't work.  I have started to read a little about using

subforms with the tables, but I am not sure where to start.  Is this the right path to go down or is there an easier way to insert columns.  If I should use subforms, is there an efficient way to change the tables to subforms?  Throughout the form there are rows that can be repeated or deleted.  I hope that I can keep this working in the same manner if possible without a lot of re-work.

Any help would be greatly appreciated.
