You have some
decisions to make.
I usually check
"smallest" and tell it to collapse empty cells less than
10 pixels wide.
I also like to
use transparent gifs to fill the empty spaces. This ensures the table
will look the same on every browser.
I also like to
center the page. I have a very large monitor in my office, and if
things are not centered, they can sometimes look very strange because
they are way over on the left side of the browser.

Dreamweaver has made my table for me with the least effort possible.
This is really a great layout tool.
