extjs checkbox

xtype: 'checkcolumn', header: 'REDACTEUR', dataIndex: 'REDACTEUR', width: 75, editor: { xtype: 'checkbox'                            }, renderer : function(value) { console.log(value);  
 
you have to manually include the css for the checkcolumn xtype like this: <link rel="stylesheet" type="text/css" href="/extjs4/examples/ux/css/CheckHeader.css">
