Perhaps that has something to do with your autocorrect options (one of which is to capitalise the first letter in each cell) or your 'Smart paste' options (one of which is to adjust formatting when pasting from Excel), but I haven't been able to figure out a combination that replicates what your experience (I ordinarily use Word's default settings).

I had time today to look it up: Word (2003) has an Auto Correct option "Capitalize first letter of table cells". It was easy to find out why the table cell capitalization happens.
