jquery - jqGrid 分组不起作用

Question

我一直无法让 jqGrid 分组选项显示在我的数据表上。我显示数据的过程是从服务器获取 json。我将它排序成一个数组，设置我的过滤器，然后在表格上显示数据。

我一直在阅读有关分组如何以不同方式处理本地和服务器数据的信息，但我不完全了解区别是什么，或者它是否与我的问题有关？

 $("#transGrid").jsGrid({
        width: '100%',
        height: 'auto',

        editing: false,
        autoload: true,
        paging: true,
        filtering: true,
        sorting: true,

        pageSize: 100,
        pageButtonCount: 10,

        grouping:true,
        groupingView : {
            groupField: ['amount'],
            groupColumnShow: [false],
            groupOrder: ['desc'],
            groupCollapse: true
        },

        rowClick: function(args){
            TransactionReceipt(args.item);
        },

        controller: {
            loadData: function (filter) {
                $('#error').empty();
