title: Return an Array of values of First <td> in Each <tr> of <tbody>
body: <p>I am trying to return an array of values for the first <code>&lt;td&gt;</code> of every <code>&lt;tr&gt;</code> within <code>&lt;tbody&gt;</code> of my table. </p>
  
  <p>A <strong>demo</strong> here (attempt, not working) <a href="http://jsfiddle.net/vJqeT/1/" rel="nofollow noreferrer">http://jsfiddle.net/vJqeT/1/</a></p>
  
  <p>My JS Code:</p>
  
  <pre><code>var newArray = $('#table1 tr:first td').map(function() {
      return $(this).html();
  });
  </code></pre>
  
  <p>My expected result in my demo is:</p>
  
  <blockquote>
    <p>[A, 1]</p>
  </blockquote>
