EXT 多个radio 横向排列

项目中用到radio,横向排了2个一切正常,排了4个就完全混乱,baidu了一下,用 layout:'column',  layout: 'form', 混合用来解决

//各个输入项
    var panelItem=  [

    		       {
                    		columnWidth:1,
                			layout: 'form',
                			items:[{
	                    		xtype:'hidden',
			                    fieldLabel: '编号',
