                    width: 150,
                    dataIndex: 'country',
                    editor: {
                         
                       items: function(value) {
                    return { 
                        xtype: 'combobox',
                        store: [[1,'In Queue'], [2,'Handling'], [3,'Complete']], 
                        value: value,
                        width: 130
                    }; 
                }
