tr class="avoid-sort" should not come in sorting!

Please help!!

You have two choices:

1. If you are using the original tablesorter, you can get this static row widget to "lock" the row in place.

2. If you are using my fork of tablesorter, you can just add a non-sortable tbody, like this (demo):

   <table> <thead>   ... </thead>  <!-- rows within this tbody are ignored --> <tbody class="avoid-sort">   <tr>     <th colspan="7">Total Revenue</th>     <td>236.41</td>   </tr> </tbody>  <tbody>   <!-- sortable rows -->   <tr>     ...   </tr> </tbody> </table> 

   then initialize the table like this:

   $(function() {     $("table").tablesorter({      theme : 'blue',      cssInfoBlock : "avoid-sort",      widgets: [ 'zebra' ]    });   });
