title: Selecting specific cells in a grid - Ext JS
body: <p>I have set up a controller here that listens for a click on a grid row:</p>
  
  <pre><code>   init: function() {
              this.control({
                  'mygrid': {
                      select: this.viewDesc //On click...
                  }
              });
          },
  </code></pre>
  
  <p>Right now this event fires no matter what cell is clicked on. However, I want to listen for the click of a specific column/cells.</p>
  
  <p>How could this be achieved?</p>
