jqGrid列的统计

 function GetGrid() {
        var selectedRowIndex = 0;
        var $gridTable = $('#gridTable');
        $gridTable.jqGrid({
            autowidth: true,
            height: $(window).height() - 136.5,
            url: "xxx/yyyy/zzzz",
            postData: { 参数1: 参数1, 参数1: 参数1},
            datatype: "json",
            colModel: [
                { label: '参数1', name: '参数1', index: '参数1', width: 100, align: 'left', sortable: true, hidden: true },

                { label: '名字', name: 'Name', index: 'Name', width: 250, align: 'left' },

                { label: 'pay1', name: 'pay1', index: 'pay1', width: 150, align: 'left' },

                { label: 'pay2', name: 'pay2', index: 'pay2', width: 100, align: 'left' },
                { label: 'pay3', name: 'pay3', index: 'pay3', width: 100, align: 'left' },
                {
                    label: '日期', name: 'Date', index: 'Date', width: 130, align: 'left', formatter: "date", formatoptions: { srcformat: 'Y-m-d', newformat: 'Y-m-d' }
                }

            ],
            viewrecords: true,
            rownumbers: true,
            shrinkToFit: false,
            gridview: true, 
            footerrow: true,
            rowNum: -1, 
            onSelectRow: function () {
                selectedRowIndex = $('#' + this.id).getGridParam('selrow');
            },
            gridComplete: function () {
                $('#' + this.id).setSelection(selectedRowIndex, false); 
                  var total_pay1=$gridTable.getCol('pay1',false,'sum');    
                  var total_pay2= $gridTable.getCol('pay2', false, 'sum');    
                  var total_pay3=$gridTable.getCol('pay3',false,'sum');   
                    $gridTable.footerData("set", { "Name": '合计', pay1: total_pay1, pay2: total_pay2, pay3: total_pay3});
                 
            },
            subGrid: true,
            //子表格的id；当子表格展开的时候，在主表格中会创建一个div元素用来容纳子表格，subgrid_id就是这个div的id
            subGridRowExpanded: function (subgrid_id, row_id) {//子表格容器的id和需要展开子表格的行id


                bindSubGrid(subgrid_id, row_id);

            }

        });

注意：以面红色文字，要一一对应，底部统计数量会对应的列显示总计

    footerrow: true 开启底部显示
