Control Panel -> Display Options -> General -> General Options. That's where you'll find the setting for the table width.
You can also do an opening table in your header and close it in the footer. Leave the control panel one at 100% and then you can just do all of your styling (centering) on the table in your heder.
Quick and dirty, just using a specified with and a center aligned table. You can change the 90% to whatever you want (a percentage, or a certain pixel width), the following should work.
I guess it was so subtle a change I could not see it. I had to change to a dark scheme to see it But just one background setting in the style editor General CSS Properties(Body)won't cut it. There would be quite a few I would think to match up then.

Or sneak in the room when she goes to sleep.LOL
