Not sure that's going to work properly. You have a strangely coded site.
You should know why tables for layouts are bad
. lol I can see why Excavator and others put this link in their signature!
Now, all you would really need to do is give an element a width less than its containing element, then in your CSS apply margin: 0 auto; to those elements you want centered. For instance the div that wraps your table(would be better to give it an id and style the id:
<div style="width: 1178px; margin: 0pt auto;">
Then for your wrapper div:
margin: 0 auto;
/* padding: 0 0 0 200px;*/
I commented out the padding because it's not needed in this case.
