title: HTML table colgroup element not working?
body: <p>I want different styles on each column of a table. I've read that you could do that by using <code>&lt;colgroup&gt;</code> or <code>&lt;col&gt;</code>, but I had no luck. I have an example <a href="http://www.jsfiddle.net/VXsbX/" rel="noreferrer">here</a>, and nothing seems to change. Am I doing something wrong? Will this work on xhtml? </p>
  
  <p>I know I could add a "class" attribute on each <code>&lt;td&gt;</code>, but that seems weak.</p>
