It looks better on an actual page but I tried to create a layout that fit your description. If either of these layouts is what you're trying to go for, I can leave the code here so you can copy it and paste it into the source mode of the page you're working on. Or none of these are it, that's also a possibility. If that's the case then, I'm not quite sure. I don't really use too many tables so hopefully it's one of these down below.
