title: how to add class to the last two TRs and apply style to the TDs inside those TRs
body: <p>I am trying to 
  1) add a class to the last two TRs of every table on the page
  2) and also style the 1st, 2nd, 5th and 8th TD of those two TRs.</p>
  
  <p>The below piece of code doesn't seem to be working. </p>
  
  <pre><code>  var rowCount = $('table tr').length;
  $('table tr').eq(rowCount - 1).addClass('myClass');
  $('table tr').eq(rowCount - 2).addClass('myClass');
  </code></pre>
  
  <p>Thanks</p>
  
  <p>BB</p>
