Not working when a header has some colspan

[fguillen]

For this table the plugin is not working, the columns get messy when you try to sort them:

<table class="table dragtable"> 
  <thead> 
    <tr> 
      <th colspan="2">Color</th> 
      <th class="draggable">First Name</th> 
      <th class="draggable">Last Name</th> 
      <th class="draggable">Username</th> 
    </tr> 
  </thead> 
  <tbody> 
    <tr> 
      <th scope="row">1</th> 
      <td>Red</td> 
      <td>Mark</td> 
      <td>Otto</td> 
      <td>@mdo</td> 
    </tr>  
  </tbody> 
</table>

Here is a jsFiddle that reproduces the issue: https://jsfiddle.net/fguillen/qnv72d5x/
