title: td:4th child css not working in firefox & IE
body: <p>I'v a table and I want to set length of the first column because it's a description.</p>
  
  <p>Due to some reason the snippet below is not working in Firefox and IE. It is working fine in Chrome.</p>
  
  <pre><code>.tblFooter td:nth-child(3) {
      width:100px !important;
  }
  
  .tblFooter td:first-child {
      width: 450px !important;
      text-align: left;
  }
  </code></pre>
