Can I place text over an image?

This may be simple, but I'm not figuring it out. I am trying to find a a way to
place text over an image in web pages using layout tables/cells in Dreamweaver
MX. For example, I've created a nav bar that's one image, and I want the actual
text links to be CSS text, so that I can change them in the future. Once I've
created a layout table and/or layout cell, Dreamweaver won't let me place
anything over it. Any help on this would be greatly appreciated!
