I don't seem to be able to do this. The Text Orientation option under the
format menu is grayed out whenever I select my captions.

Specifically, I want to have tables that are rotated 90 degrees, including
the caption. I don't want to landscape the page, because I want the headers
and footers to stay in the same place as all the other portrait pages, but
in all other ways, I want these pages to appear to be landscaped.

Any suggestions?

Thanks,
Colin
