title: Why is colspan not applied as expected
body: <p>I have a table according to below. The second row has defined three columns, one with <code>colspan=8</code> and the others with <code>colspan=1</code>. Still, the cells are not stretched according to the colspan, the "width" are a little bit more for second cell and widest for the third. </p>
  
  <pre><code>&lt;table class="floating simpletable"&gt;
      &lt;tbody&gt;
          &lt;tr&gt;&lt;td colspan="10"&gt;1st row&lt;/td&gt;&lt;/tr&gt;
          &lt;tr&gt;&lt;td colspan="8"&gt;Column 1 -&amp;gt; Least wide&lt;/td&gt;&lt;td colspan="1"&gt;2nd&lt;/td&gt;&lt;td colspan="1"&gt;3rd&lt;/td&gt;&lt;/tr&gt;
          &lt;tr&gt;&lt;td colspan="10"&gt;3rd row&lt;/td&gt;&lt;/tr&gt;
          &lt;tr&gt;&lt;td colspan="1"&gt;1st cell&lt;/td&gt;&lt;td colspan="9"&gt;4th row&lt;/td&gt;&lt;/tr&gt;
      &lt;/tbody&gt;
  &lt;/table&gt;
  </code></pre>
  
  <p>What's the problem and how to fix it?</p>
