jqGrid分组不起作用

Question

我无法获取jqGrid分组选项以显示在我的数据表中。我显示数据的过程是从服务器获取jSon。我将它排序为一个数组，设置我的过滤器，然后在表上显示数据。

我一直在阅读有关分组如何处理本地和服务器数据的不同方式，但我不完全了解差异是什么，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);
        },
