title: Using tablesorter to sort one column based on the values of another?
body: <p>I have a table that looks a little like this:</p>
  
  <pre><code>    ID    Paragraph  Title
      1     §1-1       This is the first
      2     §2-1       This is the second
  ...
      12    §10-1      This is the twelfth
  </code></pre>
  
  <p>The 'ID' column is hidden, the other two are visible. I've managed to get JQuery Tablesorter to work on sorting Paragraph and Title columns, however I would like to use the ID values when sorting the Paragraph column. Simply because the sorting is incorrect when using the Paragraph column as one can easily see. </p>
  
  <p>Is it possible to somehow make tablesorter use the ID column/values when sorting the Paragraph column?</p>
