title: How to get table cell at specified index using jQuery
body: <p>I know that I can get first or last table cell (e.g. for last row) using jQuery expression like below:</p>
  
  <p>first cell: <code>$('#table tr:last td:first')</code> or last cell: <code>$('#table tr:last td:last')</code></p>
  
  <p>But, how can I get cell at <em>specific index</em>, for example index 2, using similar expression, i.e. something like <code>$('#table tr:last td:[2]')</code> ?</p>
  
  <p>Regards.</p>
