title: How add class to last TD in table in which is rowspan. With jQuery
body: <p>Hello I have this table</p>
  
  <pre><code>&lt;table&gt;
  &lt;tr&gt;
      &lt;td&gt;n&lt;/td&gt;
      &lt;td rowspan=2&gt;n&lt;/td&gt;
      &lt;td&gt;n&lt;/td&gt;
      &lt;td&gt;n&lt;/td&gt;
  &lt;/tr&gt;
  &lt;tr&gt;
      &lt;td rowspan=2&gt;y&lt;/td&gt;
      &lt;td&gt;n&lt;/td&gt;
      &lt;td rowspan=2&gt;y&lt;/td&gt;
  &lt;/tr&gt;
  &lt;tr&gt;
      &lt;td&gt;y&lt;/td&gt;
      &lt;td&gt;y&lt;/td&gt;
  &lt;/tr&gt;
  </code></pre>
  
  <p></p>
  
  <p>and I need mark last visual TD by class <code>.last</code>. Without rowspan there isnt problem, I can use</p>
  
  <pre><code>$('table tr:last td').addClass('last');
  </code></pre>
