centering table with IE8

[xposeit]

I can't center the main table n IE8. I understand table are not a good idea to use, but It seems very simple using tables, except for the centering issues.
Anyone know how to resolve this?

You need to post your html/css

Also why do you think you should use tables? Its probably simpler to not use them, you just may not know how to.
