I understand how to center within each cell. I also know how to do this on an html page. I am familiar with tweaking the CSS and the nightandday master page (that's what we're using).
I just need a two column table with a width I have set to be centered on the main portion of the site page. I have added
.ms-rteTable-default but that changes all tables on the site.
Just need the main section of the page to do this (not the side nav section or the title bar or ribbon bar, etc) Can't figure it out.
