title: Iterate through second columns in a table in jQuery
body: <p>I have table in the dom that looks like this</p>
  
  <pre><code>&lt;div id="table"&gt;
  &lt;table&gt;
  &lt;tr&gt;
    &lt;td&gt;a&lt;/td&gt;
    &lt;td&gt;b&lt;/td&gt;
    &lt;td&gt;c&lt;/td&gt;
    &lt;td&gt;d&lt;/td&gt;
  &lt;/tr&gt;
  &lt;tr&gt;
    &lt;td&gt;a&lt;/td&gt;
    &lt;td&gt;b&lt;/td&gt;
    &lt;td&gt;c&lt;/td&gt;
    &lt;td&gt;d&lt;/td&gt;
  &lt;/tr&gt; 
  &lt;/div&gt;
  </code></pre>
  
  <p>I want to iterate through this table, such as <code>$('#table').each(function(){})</code> but I only want to iterate through the second column.  So the ones which in this example have a value of b.</p>
  
  <p>Any ideas how to do this?</p>
  
  <p>Thank you!</p>
