Resizing cells in the table

Resizing cells in the table

Hi,
I have table like this:
<table>
<tr>
  <td><div class="drop">a</div></td>
  <td><div class="drop">a</div></td>
  <td><div class="res">aa</div></td>
  <td><div class="drop">a</div></td>
  <td<div class="drop">a</div></td>
</tr>


and jQuery code:
$(".res").resizable({handles: 'e, w', helper: 'res-hover'});


And I would like to do this: If you resize the block res, it joins with selected block drop, so the it will be one cell in table. I try to use this:
    $(".res").resize(function(){     
      $(".drop").bind("mouseenter",function(){
        $(this).addClass("hover");
        // there will be joind cells
      });     
    });


, but if I once resize the block called res, it always select block called drop and I'd like to split the cells only if I just resizing the block called res. I hope, that you understand my problem:-) Thanks for advise
