Table Drag and drop

hi Guys,
       I am new to Jquery I learnt to drag and drop table but I have a question, if a row has 4 td I want to move 3 how can I do that

Jquery
 
<script type="text/javascript" src="js/jquery-1.4.2.min.js"></script>
<script type="text/javascript" src="js/jquery.tablednd.js"></script>
<script type="text/javascript">
<!-- <![CDATA[
$(function(){
  $("#sortable-tbl").tableDnD();




  $('#frm-sort').submit(function(){
    var sRowOrder = "";
    $("#sortable-tbl tr").each(function(i,o){
    if (sRowOrder.length) {
      sRowOrder += "," + o.id;
    } else {
      sRowOrder = o.id;
    }
    });
    $('#sort_order').val(sRowOrder);
  });
});
// ]]> -->
</script>












 
HTML
 
<table id="sortable-tbl" border="1">
<cfloop from="#startTime#" to="#endTime#" index="i" step="#CreateTimeSpan(0,0,30,0)#">
<tr>
<td>#TimeFormat(i, "hh:mm tt")#[ I dont want to move this TD]</td>
