4.datagrid要点

columns:[[]],两个括号是因为可以有两行标题:

columns:[[
            {field:'name',title:'绰号',width:100}
        ],
        [
            {field:'name',title:'姓名',width:100}
        ]]

处理object在colomun中显示问题:

{field:'dept',title:'部门',width:100,formatter:function (value,row,index) {
                    return value.name;
                }
    
}

处理单个单元格背景色:

{field:'state',title:"状态",width:100,formatter:function (value,row,index) {
                    return value?"在职":"离职";
    },styler:function (value,row,index) {
                    if(!value){
                        return 'background-color:pink;color:red'
                    }
            }
}
