title: How can I set the style in ExtJs actionColumn items?
body: <p>I have the next piece of code</p>
  
  <pre><code>{
  xtype: 'actionColumn',
  id: 'act_id',
  width: 30,
  flex: 0,
  items: [{
       getClass: function(v, meta, record) {
         if(record.get('blahblah') == true)
           return 'aClassName';
         else
           return 'aOtherClassName';
       }
     }]
  }
  </code></pre>
  
  <p>Ok this piece of code working fine, but I like adding a style in line in my icon, but when I use something like:</p>
  
  <pre><code>{
  xtype: 'actionColumn',
  id: 'act_id',
  width: 30,
  flex: 0,
  items: [{
       getClass: function(v, meta, record) {
         if(record.get('blahblah') == true)
           return 'aClassName';
         else
           return 'aOtherClassName';
       },
       style: {'width':'16px'}
     }]
  }
  </code></pre>
  
  <p>Nothing happen. I try a 1000 different ways but nothing, and in the ExtJs 4 I can't find anything about this.</p>
