title: treecolumn renderer with icon - extjs 4.2.1
body: <p>I'm building simple application using Ext Scheduler (<a href="http://www.bryntum.com/products/scheduler/" rel="nofollow noreferrer">http://www.bryntum.com/products/scheduler/</a>).
  I'm trying to add custom renderer for treecolumn that will have icon of person in tree.
  <img src="https://i.stack.imgur.com/0HNnD.png" alt="enter image description here"></p>
  
  <p>I've created rendered for that column:</p>
  
  <pre><code>renderer: function (v, m, r) {
              if (r.get('leaf')) {
                  return '&lt;div style="float: left"&gt;' +
                      r.get('Name') +
                      '&lt;/div&gt;'+
                      '&lt;img data-qtip="&lt;img src=iconUrl.png width=60px height=60px/&gt;" '+
                      'src="iconUrl.png" '+
                      'width="20px" height="20px" style="float: right; margin-right: 5px"/&gt;';
              }
              return v;
          }
  </code></pre>
  
  <p>This looks OK, but for long names I get unwanted look:</p>

  <p>Looking thrue code I found some unwanted markup:
  <img src="https://i.stack.imgur.com/eXVmo.png" alt="enter image description here"></p>
  
  <p>What I need is almost identical renderer as in standard treecolumn, but I need to add extra icon on right of that column - employee image thumbnail.</p>

  <p>I was searching over docs and I found out that there is private property called <code>cellTpl</code> (<a href="http://docs.sencha.com/extjs/4.2.1/source/Column2.html#Ext-tree-Column" rel="nofollow noreferrer">http://docs.sencha.com/extjs/4.2.1/source/Column2.html#Ext-tree-Column</a>)</p>
  
  <p>but I don't know how should I change this and should I change this at all because it is marked as private on top.</p>
  
  <p>How should I change that renderer to get effect as on last image?</p>
  
  <p>Here is some jsfiddle to play: <a href="http://jsfiddle.net/Misiu/gwFdr/" rel="nofollow noreferrer">http://jsfiddle.net/Misiu/gwFdr/</a></p>
