title: jQuery DataTables: how to sort by custom parameter value rather than the content of the cell?
body: <p>I have a pretty common use case where I show the formatted price in a Price column, eg. "20,000.00". So when I try to sort it, it treats it as a string and doesn't sort well:</p>
  
  <ul>
  <li>10.00</li>
  <li>20,000.00</li>
  <li>5,000.00</li>
  </ul>
  
  <p>Can I make it so that it would sort by the data- parameter value, which would be non-formatted float number?</p>
  
  <p>And related to this question: how do you disable sorting for the given column? I'm using DataTables 1.9.4.</p>
