Well, you can write a VBA procedure that would compare the rows and/or
cells and delete and/or flag (color?) those rows that were dups so you
could deal with them.
Manually, just sort the table once merged and delete those rows you
don't want.

This article by ibby has some code (and a link to a "wildcard replacements" article that shows how to remove duplicate *paragraphs* if you can turn the table into text without problems): http://www.word.mvps.org/faqs/macrosvba/DeleteDupRows.htm
I guess you can sort the table? Else, you'd need to insert an extra column, number that, sort, delete duplicates, sort using the numbered column, and then delete that column again.
