title: Append <th> Class to <td> in the Same Column
body: <p>I've been searching all over the net for hours now but I still can't figure this out.</p>
  
  <pre><code>&lt;table&gt;  
    &lt;tr&gt;  
      &lt;th class="name"&gt;Name&lt;/th&gt;
      &lt;th class="age"&gt;Age&lt;/th&gt;
      &lt;th class="nick"&gt;Nick&lt;/th&gt;
    &lt;/tr&gt;  
  
    &lt;tr&gt;  
      &lt;td&gt;John&lt;/td&gt;
      &lt;td&gt;30&lt;/td&gt;
      &lt;td&gt;Johnny&lt;/td&gt;
    &lt;/tr&gt;
  
    &lt;tr&gt;  
      &lt;td&gt;Robert&lt;/td&gt;
      &lt;td&gt;35&lt;/td&gt;
      &lt;td&gt;Bob&lt;/td&gt;
    &lt;/tr&gt;
  &lt;/table&gt;
  </code></pre>
  
  <p>Is there any way to append the classes from those headers to the TD tags in the same column?</p>
