You can use Word's Catalogue/Directory Mailmerge facility for this (the terminology depends on the Word version). To see how to do so with any mailmerge data source supported by Word, check out my Microsoft Word Catalogue/Directory Mailmerge Tutorial at:
http://windowssecrets.com/forums/sho...merge-Tutorial
or
http://www.gmayor.com/Zips/Catalogue%20Mailmerge.zip

The tutorial covers everything from list creation to the insertion & calculation of values in multi-record tables in letters. Do read the tutorial before trying to use the mailmerge document included with it.

For a worked example that approximates what you're after, see:

Although the example there uses a 4-column section layout to achieve the effect, the principle applies to other columns layouts as well.

Alternatively, you may want to try one of the Many-to-One Mail Merge add-ins, from:
