Incorrect cell selection with rowspan (jQuery)
<p>Markup:</p>

<pre><code>&lt;tr&gt;
  &lt;td colspan="3" rowspan="4"&gt;1&lt;/td&gt;
  &lt;td&gt;2&lt;/td&gt;
  &lt;td&gt;3&lt;/td&gt;
&lt;/tr&gt;
</code></pre>

<p>jQuery:</p>

<pre><code>$("table tr td:first").addClass("first-col-cell");
$("table tr td:last-child").addClass("last-col-cell");
</code></pre>

<p>...according to jQuery documentation :first selector should only select the first td (1) but it also selects other 2.</p>

<p>Thanks</p>
