Add class to DIV with TD Wrapping
<p>Im trying to add a class to a TD which contains a DIV.</p>

<p>HTML:</p>

<pre><code>&lt;td&gt;
  &lt;div class="report"&gt;
    Some HTML
  &lt;/div&gt;
&lt;/td&gt;
</code></pre>

<p>My jQuery:</p>

<pre><code>$('.report').prev().addClass('wrapper');
</code></pre>

<p>What am I doing wrong?</p>
