Looks like just a matter of splitting your tables up even more than they are. The first table here, set that to border=0 and then add a table above that line with the border=2. That will set your outside border for the page. Then, just do table w/in a table to set the borders the way you want them. It's a bit of extra code, but as long as you label your tables (using <!-- comments), it should make editing them later on easier.
