sort

Hi,
 
I have the table is displayed the results from the query.  It worked fine the sort by asc or desc.  Is there the way to find out which field is user is clicked on for sorting? My code below has 4 fields.  I want to able to tell which field is user is clicking such as, Type or Number or Result....?
 
Thanks
 
<script type="text/javascript">
$(document).ready(function() {
 $("#thetable").tablesorter({
        // sort on the first column and third column, order asc
        sortList: [[2,0]]
     });
    }
);
</script>
  <table width="100%" border="0" align="left"  id="thetable" class="tablesorter">
<thead>
<tr>
    <th nowrap="nowrap">Type</th>
    <th nowrap="nowrap">Number</th>
     <th nowrap="nowrap">Results</th>
      <th nowrap="nowrap">Date</th>
</tr>
</thead>
















<tbody>
<tr>
    <td>#type#</td>
   <td>#number#</td>
   <td>#results##</td>
   <td>#date#</td>
</tr>
</tbody>
