title: jQuery selector to last row first column
body: <p>I'm trying to change the value of the first cell on the last row of a table.</p>
  
  <p>My code is:</p>
  
  <pre><code>$(document).ready(function() {
      $('table.class tr:last td:first').html('Value');     
  });
  </code></pre>
  
  <p>But that code changes nothing, but if I put without the :last and :first he fills the all table with 'Value'. What am I doing wrong?</p>
  
  <p>Edit: My bad, the code works fine, but just for the last table with class 'class'.What I need it's to do that on every tables with that class. Any idea? </p>
