Arrrrgh! I'm in 2007 as well, and spent over an hour trying to help another
staff figure this issue out. And while this request for information is a bit
outdated, I thought I would share in case someone does a search and is having
the same issues. After working with a table in 2007 for what seemed like
eons and trying to figure out why I couldn't get the header row to show on
the following pages, I finally figured it out and I kick myself in the pants
for not figuring it out sooner.
On the contextual Table Tools tab, go to LAYOUT/TABLE/PROPERTIES, then
select the Table tab, and click the bottom left icon for "None" under "Text
Wrapping."
