title: jquery table sorter sort issues
body: <p>Good evening all,</p>
  
  <p>I'm trying to implement jquery table sorter, all seems fine and sorts by columns, however for some reason the date (default) column doesn't sort by the date format I'm using. This is the code:</p>
  
  <pre><code>&lt;script type="text/javascript"&gt;
  $(document).ready(function() 
      { 
      $("#myTable").tablesorter( {sortList: [[0,0]]} ); 
      } 
  ); 
  &lt;/script&gt;
  </code></pre>
  
  <p>The date column is the first column and the dates are written in this format:
  2 June 11
  15 October 11 etc</p>
  
  <p>In addition, from the above code, how would you disable the option to sort a particular column (column 6, which is the final column)? Can't for the life of me figure it out!</p>
  
  <p>Failing this, I'm more than happy to use the date format as dd/mm/yyyy if it's easier?</p>
