title: Table row length in javascript show one extra
body: <p>I have a table with an id of <code>myPicks</code> and when I execute the code below, the result is always one more than of the number of rows I have? Is this how it's suppose to behave? Thanks.</p>
  
  <pre><code>var table =document.getElementById("myPicks");
  var rowCount = table.rows.length;
  </code></pre>
