我尝试使用jqgrid创建一个网格，该网格最初没有数据，但具有固定大小，其中列的总宽度大于网格宽度，因此用户只能滚动标题。用户将单击一个按钮，该按钮将数据填充到网格中。这听起来可能类似于已经回答的问题jqGrid vertical scrollbar
然而，在这种情况下，数据已经存在了。我最初没有数据，希望网格具有滚动条。我注意到，只有填充数据后，才会创建class为. ui-jqgrid-bdiv的div。
这是jqgrid中的一个bug吗？有什么解决方法吗？

下面是代码：
javascript语言

$(document).ready(function () {
    $("#results").jqGrid({
        datatype: "local",
        height: 150,
        scroll:true,
        width:300,
        shrinkToFit:false,
        colNames: ['Inv No', 'Date', 'Client', 'Amount', 'Tax', 'Total', 'Notes'],
        colModel: [
            { name: 'id', index: 'id', width: 160, sorttype: "int" },
            { name: 'invdate', index: 'invdate', width: 90, sorttype: "date" },
            { name: 'name', index: 'name', width: 100 },
            { name: 'amount', index: 'amount', width: 80, align: "right", sorttype: "float" },
            { name: 'tax', index: 'tax', width: 180, align: "right", sorttype: "float" },
            { name: 'total', index: 'total', width: 280, align: "right", sorttype: "float" },
            { name: 'note', index: 'note', width: 150, sortable: false }
           ],
       });
            var mydata = [
                            { id: "1", invdate: "2007-10-01", name: "test", note: "note", amount: "200.00", tax: "10.00", total: "210.00" },
                            { id: "2", invdate: "2007-10-02", name: "test2", note: "note2", amount: "300.00", tax: "20.00", total: "320.00" },
                            { id: "3", invdate: "2007-09-01", name: "test3", note: "note3", amount: "400.00", tax: "30.00", total: "430.00" },
                            { id: "4", invdate: "2007-10-04", name: "test", note: "note", amount: "200.00", tax: "10.00", total: "210.00" },
                            { id: "5", invdate: "2007-10-05", name: "test2", note: "note2", amount: "300.00", tax: "20.00", total: "320.00" },
                            { id: "6", invdate: "2007-09-06", name: "test3", note: "note3", amount: "400.00", tax: "30.00", total: "430.00" },
                            { id: "7", invdate: "2007-10-04", name: "test", note: "note", amount: "200.00", tax: "10.00", total: "210.00" },
                            { id: "8", invdate: "2007-10-03", name: "test2", note: "note2", amount: "300.00", tax: "20.00", total: "320.00" },
                            { id: "9", invdate: "2007-09-01", name: "test3", note: "note3", amount: "400.00", tax: "30.00", total: "430.00" }
                            ];
            //if you uncomment this, the scrollbars would appear
            /*for (var i = 0; i <= mydata.length; i++)
                $("#results").jqGrid('addRowData', i + 1, mydata[i]);*/
        });

超文本标记语言

<div>
    <table id="results"></table>
</div>

EDIT：为了更清楚，在上面的例子中，我想水平滚动标题。当数据被填充时，标题在垂直滚动时应该保持静态，而在水平滚动时应该与数据一起。
谢谢!
