title: How to get value of table cell with jquery from checkbox using absolute row number
body: <p>I have a table 'mytable' that looks like:</p>
  
  <pre><code> &lt;tr&gt;
        &lt;td&gt;&lt;input type="checkbox" name="check[]" value="11"&gt;&lt;/td&gt;   
        &lt;td&gt;11&lt;/td&gt;
        &lt;td&gt;2014-11-06 18:49:26&lt;/td&gt;
        &lt;td&gt;MESSAGE&lt;/td&gt;
        &lt;td&gt;&lt;/td&gt;
        &lt;td&gt;MATCH5&lt;/td&gt;
        &lt;td&gt;NO MATCH&lt;/td&gt;
        &lt;td&gt;NO MATCH&lt;/td&gt;
   &lt;/tr&gt;
  </code></pre>
  
  <p>I want to get the value of column 4 "MESSAGE" from a row if its checked</p>
  
  <p>as you can see each row begins with a checkbox which  have a value. however the value is non-sequential so I can't just go with the checkbox value (which I have been getting with</p>
  
  <pre><code>var IDs = $('input:checked').map(function(){
      return $(this).val();
  }).get();)
  </code></pre>
  
  <p>I need some way of counting table rows then I can use something like:</p>
  
  <pre><code> var id= $("#myTable tr").eq(ID).find('td').eq(4).val()
  </code></pre>
  
  <p>How to do this?</p>
