title: DataTables - Not working when added colspan for the last column
body: <p>I've a problem using DataTables. When i add colspan for the last column, the datatable plugin wont get applied to the table. If i remove the colspan for the last one and put it to any other column, it works.</p>
  
  <p>For example - </p>
  
  <pre><code>&lt;table width="100%" border="0" cellspacing="0" cellpadding="0" id="stu_data_table"&gt;
     &lt;thead&gt;
        &lt;tr&gt;    
          &lt;th&gt;&amp;nbsp;&lt;/th&gt;
          &lt;th colspan="2"&gt;&amp;nbsp;&lt;/th&gt;
          &lt;th colspan="2"&gt;&amp;nbsp;&lt;/th&gt;
        &lt;/tr&gt;
     &lt;/thead&gt;
     &lt;tbody&gt;
        &lt;tr&gt;
          &lt;td&gt;&amp;nbsp;&lt;/td&gt;
          &lt;td&gt;&amp;nbsp;&lt;/td&gt;
          &lt;td&gt;&amp;nbsp;&lt;/td&gt;
          &lt;td&gt;&amp;nbsp;&lt;/td&gt;
          &lt;td&gt;&amp;nbsp;&lt;/td&gt;
        &lt;/tr&gt;
     &lt;/tbody&gt;
  &lt;/table&gt;
  
  $('#stu_data_table').dataTable({
  });
  </code></pre>
  
  <p>Any solution for this?</p>
