title: CSS3 Ribbon in HTML table
body: <p>I refer to the tutorial of <a href="http://css-tricks.com/snippets/css/ribbon/" rel="nofollow noreferrer">CSS3-Tricks Ribbon tutorial</a>.</p>
  
  <p>I'd like to adjust the <code>th</code> element inside a table with CSS3 so that it looks like the ribbon in the tutorial.</p>
  
  <p>I've set up a <a href="http://jsfiddle.net/qU7Ba/" rel="nofollow noreferrer">JSFiddle</a> to test it, but unfortunately I can't do it. Can you help me?</p>
