title: Colspan spanning 2.5 columns?
body: <p>I have a table with 5 columns. The final row should have two cells, spaced equally. </p>
  
  <p>Ideally, I would like to use <code>&lt;td colspan="2.5"&gt;</code> - whats the most elegant way to do this?</p>
  
  <p>The table has a border of 1, so using  </p>
  
  <pre><code>&lt;td colspan=2"&gt;abc&lt;/td&gt;
  &lt;td&gt;&lt;/td&gt;
  &lt;td colspan=2"&gt;def&lt;/td&gt;
  </code></pre>
  
  <p>looks ugly</p>
