title: IE: nth-child() using odd/even isn't working
body: <p>My table (that works perfectly on Chrome, FireFox and Opera) is not displaying correctly on Internet Explorer.</p>
  
  <p>The background remains white! (I am using IE-8)</p>
  
  <p><strong>CSS code:</strong></p>
  
  <pre><code>/*My Table*/
  .my_table{
  border-collapse:collapse;
  font:normal 14px sans-serif,tahoma,arial,verdana;
  margin:5px 0;
  }
  
  .my_table th{
  color:#fff;
  background:#5E738A;
  border:1px solid #3C5169;
  text-align:center;
  padding:4px 10px;
  }
  
  .my_table td{
  color:#555;
  border:1px solid #C1CAD4;
  text-align:center;
  padding:2px 5px;
  }
  
  .my_table tr:nth-child(even){
  background:#E6EDF5;
  }
  
  .my_table tr:nth-child(odd){
  background:#F0F5FA;
  }
  </code></pre>
