title: Fast Javascript Table sorter?
body: <p>I have a table with about 250 rows (may double within 6 months), and 50 columns on <a href="http://www.reviews-web-hosting.com/wizard.html" rel="noreferrer">this page</a> (warning: slow with IE). I'm using the <a href="http://tablesorter.com/docs/" rel="noreferrer">JQuery Table sorter</a>. But it is too slow with IE 7: it gives a warning about a slow javascript, and ask if I want to stop it. I've spent a lot of time to improve performances, so it works fine for all other browsers:</p>
  
  <ul>
  <li>sort text and digit only</li>
  <li>removed all but 2 parsers</li>
  <li>created an extra table that contains all the values, much faster than doing node.textContent() for each cell</li>
  <li>removed lowercase, trim, etc.</li>
  </ul>
  
  <p>My version of the javascript is <a href="http://www.reviews-web-hosting.com/js/jquery.tablesorter.js" rel="noreferrer">here</a>. I think I cannot optimize it much more. I am looking for another fast implementation of a table sorter, or any good optimization I may have forgot, so that IE 7 won't complain about the execution time.</p>
  
  <p><strong>Edit:</strong> I've disabled sorting on 35 columns, it is still too long for IE</p>
