If using the popular plugin CSS3 Web Pricing Tables Grids, Pro’s theme CSS modifies its tables by using the same class names as the plugin.
Specifically:
#cs-content *, #cs-content *:before, #cs-content *:after {
-webkit-box-sizing: border-box !important;
-moz-box-sizing: border-box !important;
box-sizing: border-box !important;
If the box-sizing line is commented out, the layout is fixed and looks as it did prior to 1.2.x. Not sure if Pro or the plugin author is guilty of not using best practices or if it’s just a coincidence and we’re at a stalemate to see who balks first, but wanted you to know.
