<p>Bug <a href="https://bugs.webkit.org/show_bug.cgi?id=87536">87536</a>: REGRESSION(r111742): box-sizing: border-box doesn't work on fixed table layout</p>
<p>Testing that a column group's fixed width should apply to the cell's border-box and not impacted by the cell's box-sizing.</p>
<p>You should see 4 100px * 100px cells with green borders.</p>
