关键点：
1.scroll: 1, //虚拟滚动，解决大数据一次性加载慢的问题，同时解决分页

2.function merge(names)//自定义函数

$(function () {       //查询       $("#querybtn").click(function () {                var prm = {};                $("#querytb td [name]").each(function (ind, o) {                    prm[o.name] = $(o).val();                 });                if ($("#jqgrid").data("jqgrid")) {//已经初始化                    $("#jqgrid").jqGrid("setGridParam", {                         "postData": prm })                    .trigger("reloadGrid");                } else {                    $("#jqgrid").jqGrid({                        url: ‘SCHandler.ashx?action=SCResult2‘,                        caption: "点检结果",                        datatype: "json",                        pager: "#pager", postData: prm,                        height: ($(window).height() - 210),                         colNames: ["rid", "系统", "设备名称", "部位", "项目", "点检内容", "点检时间", "点检结果", "结果说明", "处理方式", "处理结果", "点检人", "点检单位"],                        colModel: [{ name: "rid", hidden: true, key: true },                            { index: "系统", name: "系统", width: 80 },                            { index: "设备名称", name: "设备名称", width: 80 },                            { index: "部位", name: "部位", width: 80 },                            { index: "项目", name: "项目", width: 80 },                            { index: "点检内容", name: "点检内容", width: 80 },                            { index: "点检时间", name: "点检时间", width: 100 },                            { index: "点检结果", name: "点检结果", width: 60 },                            { index: "结果说明", name: "结果说明" },                            { index: "处理方式", name: "处理方式" },                            { index: "处理结果", name: "处理结果" },                            { index: "点检人", name: "点检人" },                            { index: "点检单位", name: "点检单位", hidden: true }                    ],                        rowNum: 50,                         gridComplete: function () { merge(["系统", "设备名称", "部位", "项目","点检内容"]); },                        cmTemplate: { editable: false, sortable: false, width: 80 }, scroll: 1,                         viewrecords: true, gridview: true                    }).bindKeys().data("jqgrid", true);                }            });        });        function merge(names) {            var trs = $("#jqgrid>tbody>tr:gt(0)");            $.each(names, function (ind, name) {                var bg = trs.eq(0).children("[aria-describedby=‘jqgrid_" + name + "‘]"),                    index = bg.index(),                    rowsp = 1;                trs.slice(1).each(function (ind2, tr) {                    var me = $(tr).children("td").eq(index);                    if (bg.text() === me.text()) {                        rowsp++;                        me.hide();                    } else {                        bg.attr("rowspan", rowsp);                        bg = me;                         rowsp = 1;                    }                    bg.attr("rowspan", rowsp);                });            });        }
