How to get the data in this example
<p>Given the code like this</p>

<pre><code>&lt;table&gt;
  &lt;tr&gt;
    &lt;td&gt;1&lt;/td&gt;
    &lt;td&gt;e&lt;/td&gt;
    &lt;td&gt;a&lt;/td&gt;
  &lt;/tr&gt;
  &lt;tr&gt;
    &lt;td&gt;2&lt;/td&gt;
    &lt;td&gt;e&lt;/td&gt;
    &lt;td&gt;c&lt;/td&gt;
  &lt;/tr&gt;
   ...
&lt;/table&gt;
</code></pre>

<p>The first cell of every row is the id (it's unique)
If the input is value of the id, how can I get the value of the third cell in this row</p>

<pre><code>Example: input 1 -&gt; output a
         input 2 -&gt; output c
</code></pre>

<p>How can I do it with Jquery?</p>
