title: Efficient way of finding index of row?
body: <p>I am getting the index of a row by doing this:</p>
  
  <pre><code>row.parent().children("tr").index(row)
  </code></pre>
  
  <p>Is there a more efficient way to find the index? I have hundreds of rows so it is killing my performance that I have to select all rows just to find the index.</p>
