Anyone have the table layout for a two column theme?

I'm fairly new to designing themes and am having a hell of a time moving everything around to get the layout to appear correctly.

I've designed a two column theme where I want the right and the left columns on the left with all of the center content on the right.

The problem I'm having is that I think I've figured that the content layout is actually several tables nested inside each other (am I right) and I'm not sure which IF statement or TD ID goes where if I move things to where I want them....does that make sense?

So, if anyone has a two column table layout I'd REALLY appreciate it.
