Extjs 5 rowediting only in some conditions

Good day all, I have a table in which I use the rowediting feature, and I have this column:

{
  text: 'CPL Object',
  dataIndex: 'CPLObj',
  flex: 1,
  editor: {
           allowBlank: false
   }

}

now, I'd like to make this column editable, only if another column has a certain value, let's say if the 'model' column has 'CPU' as value. Otherwise I'd like to Not have the editor for this value.

Is that possible?

do you mean your using grid? Have you tried adding a formula on your viewModel for checking if the model column you wish to check do have a value? Maybe something like:

Viewmodel:
   checkvalue: function(get){
     var x = true;
     if (get('current.model' !== ''){ 
        x = false 
     } 
     return x;
    }


   ViewController: (on your binding)
   column: {
     readonly: '{checkvalue}' 
   }
