This would be much easier done in Excel, which could only require a quick
copy/paste (assuming you have Excel). See:

I am certain that doing it in Word would require VBA, where at least you'll
have a choice with Excel.

I am making a merge form in word 97 and the source data was created as a
.doc
file using mail merge helper. there are 6 columns, 5 of which can contain
duplicate information. 1 column, however, cannot. The column title is ID#,
and each person has a unique #. How can I prevent entering duplicate
entries
of ID#'s in a word table?
