datagrid如何变成行显示？每行显示一个字段。

    <table id="pg" title="定存宝详情"></table>
     var rows = [
        { "name": "单号", "group": "帐号", "field":"pid"},
        { "name": "金额", "group": "帐号", "field": "project_amount"}
    ];
    $('#pg').propertygrid({
        width: 298,
        height: 'auto',
        showGroup: true,
        scrollbarSize: 0,
        url:'../php'
        columns: [[
                { field: 'name', title: 'Name', width: 100, resizable: true },
                { field: 'value', title: 'Value', width: 100, resizable: false }
        ]]
    });
    $('#pg').propertygrid('loadData', rows);
