Standard HTML question? Tables...?

[Kaiden]

First of all, since I'm not sure how well I can explain it, this is basically what I want:

Notice how all the text and pictures are seperated into their own phantom tables, not right on the background? That's what I want. I've done that, but I'm not sure how to control the size of the tables.

With the table set-up I have now, the table almost reaches from one side to the other and it leaves most of the page blank. I want a table about the same size as the one on the comic I linked too. The part with the actual comic on it.

How would I do this? What about the green tables on the sides, with the ads on them- how would I make my tables that size?

Thanks
I'm looking for the codes. Even without the exact dimensions, the codes to control the table sizes would help a lot.
