ignore sorting on a particular column tablesorter

Can I ignore sorting on a particular column in jquery tablesorting plugin? So basically when the page is loaded I do not not want any sorting done on the column "Search" because it contains images and does some javascript processing of its own and this slows down my sorting considerably. Here is my code: ``` <script type="text/javascript"> jQuery(document).ready(function() { jQuery("table").tablesorter({ }); ``` }); ``` puts "<table cellspacing=\"1px\" class=\"tablesorter\" >" puts "<thead>" puts "<tr>" puts "<th>Search</th>" puts "<th>Sub-App</th>" puts "<th>Division</th>" puts "<th>Region</th>" puts "<th>Market</th>" puts "<th>Language</th>" puts "<th>Function</th>" puts "<th>LOB</th>" puts "<th>Term</th>" puts "<th>Center</th>" puts "</tr>" puts "</thead>" puts "<tbody>" puts "<tr>" puts "<td id=\"$cellID\">" puts "<img src=\"images/magnifier.gif\" style=\"cursor:pointer\" onclick=\"showRouting({'spec':'${specific}', 'id':'${mkt_id}', 'name':'${mkt_name}', 'xfer':'${xfertype}', 'cell':'${cellID}'})\"</img>" puts "</td>" puts "<td>$level</td>" puts "<td>$div_name</td>" puts "<td>$reg_name</td>" puts "<td>$link</td>" puts "<td>$lang</td>" puts "<td>$func</td>" puts "<td>$lob</td>" puts "<td>$term</td>" puts "<td>$ctr_name</td>" puts "</tr>" puts "</tbody>" puts "</table>" ```
