Sorry, that should have been:

    $($('#tableID')[0].rows[x].cells[y]).text();

<table id="fred">
  <tr><td>sally<td>Sam
</table>
<script type="text/javascript" src="jquery.js"></script>
<script>
  alert( $($('#fred')[0].rows[0].cells[0]).text() );
</script>


But I screwed up my speed test, that is actually no faster than using
a CSS style selector.  The fast way is:

<script>
  function getText(el){
    if (typeof el.textContent == 'string') return el.textContent;
    if (typeof el.innerText == 'string') return el.innerText;
  }

  alert( getText(document.getElementById('fred').rows[0].cells[0]) );
</script>
