ext中grid根据数据不同显示不同样式

var clsRender = function(value){
    if (value == ‘male‘) {  
        return "<span style=‘color:red;font-weight:bold;‘>红男</span>";  
    } else {  
        return "<span style=‘color:green;font-weight:bold;‘>绿女</span>";  
    }  
}},  

    var cm = new Ext.grid.ColumnModel([  
        {header:‘编号‘,dataIndex:‘id‘},  
        {header:‘性别‘,dataIndex:‘sex‘,renderer:clsRender},  
        {header:‘名称‘,dataIndex:‘name‘},  
        {header:‘描述‘,dataIndex:‘descn‘,renderer:renderDescn}  
    ]);
