title: How do I iterate through table rows and cells in JavaScript?
body: <p>If I have an HTML table...say</p>
  
  <pre><code>&lt;div id="myTabDiv"&gt;
  &lt;table name="mytab" id="mytab1"&gt;
    &lt;tr&gt; 
      &lt;td&gt;col1 Val1&lt;/td&gt;
      &lt;td&gt;col2 Val2&lt;/td&gt;
    &lt;/tr&gt;
    &lt;tr&gt;
      &lt;td&gt;col1 Val3&lt;/td&gt;
      &lt;td&gt;col2 Val4&lt;/td&gt;
    &lt;/tr&gt;
  &lt;/table&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>How would I iterate through all table rows (assuming the number of rows could change each time I check) and retrieve values from each cell in each row from within JavaScript?</p>
