jQuery Select first and second td
<p>How can I add a class to the first and second td in each tr?</p>

<pre><code>&lt;div class='location'&gt;
&lt;table&gt;
&lt;tbody&gt;
&lt;tr&gt;
&lt;td&gt;THIS ONE&lt;/td&gt;
&lt;td&gt;THIS ONE&lt;/td&gt;
&lt;td&gt;else&lt;/td&gt;
&lt;td&gt;here&lt;/td&gt;
&lt;/tr&gt;
&lt;tr&gt;
&lt;td&gt;THIS ONE&lt;/td&gt;
&lt;td&gt;THIS ONE&lt;/td&gt;
&lt;td&gt;else&lt;/td&gt;
&lt;td&gt;here&lt;/td&gt;
&lt;/tr&gt;
&lt;/tbody&gt;
&lt;/table&gt;
&lt;/div&gt;
</code></pre>

<p>For the first td, this does nothing?</p>

<pre><code>$(".location table tbody tr td:first-child").addClass("black");
</code></pre>

<p>Can I also use second-child?</p>
