ligerUI合并单元格

我的方法：

//ligerUI设置表格

function f_setGrid(cloumns){
    var cloumns = [
        { name: 'UserName', display: '名称', 200},
        { name: 'OutfallsName', display: '点位', 280},
        { name: 'Num', display: '时长(单位：分钟)', 200},
        { name: 'Sum', display: '总时长(单位：分钟)', 200}
    ]

    gridManager = $("#maingrid").ligerGrid({
        columns: cloumns,
        width : '99%',
        height : '99%',
        pageParmName:'pageno',
        //page: 1,
        pageSize:20,
        rownumbers :true,
        root:'rows',
        record:'total',
        onAfterShowData: function (s) {
            setTimeout(function () {
            $('#maingrid .l-grid-body-table tbody').rowspans('UserName','Sum' , gridManager);//rowspan传入    要合并的列的列名 
　　　　　　　//$('#maingrid .l-grid-body-table tbody').rowspans('UserName' , gridManager);//rowspan传入    要合并的列的列名 
　　　　　　 //$('#maingrid .l-grid-body-table tbody').rowspans('Sum' , gridManager);//rowspan传入 要合并的列的列名
            });
        }
    });
    f_reload();//加载表格数据
}  

//载入数据源的方法
function f_reload() {
    var para = $("#form1").serializeArray();

    var formData = new FormData(document.getElementById("form1"));
    gridManager.setOptions({
        url : action+'!getData.action?rnd='+Math.random(),
        parms :$("#form1").serializeArray(), //直接提交表单
        dataAction : 'server',
        dataType : 'server'
    });
}

//两列

$.fn.extend({
        rowspans:function(colname, colname2, tableObj){
            var colIdx,colIdx1;
            for (var i = 0, n = tableObj.columns.length; i < n; i++) {   //判断第几列
                if (tableObj.columns[i]["columnname"] == colname) {
                    colIdx = i-1;
                }
                if (tableObj.columns[i]["columnname"] == colname2) { //同上
                    colIdx1 = i-1 ;
                }
            }
            return this.each(function () {
                var that,rt;
        
                $('tr', this).each(function (row,element) {  //遍历表格
                    var a = $(element).children();   
                    var gg = $(a.eq(colIdx));
                    var qq = $(a.eq(colIdx1));
            
                    if(that != null && $(that).html() == $(gg).html()){
            
                        //合并单元格操作
                        rowspan = $(that).attr("rowSpan");
                        rowspan1 = $(rt).attr("rowSpan");
                        if (rowspan == undefined) {   //
                            $(that).attr("rowSpan", 1);
                            $(rt).attr("rowSpan", 1);
                            rowspan = $(that).attr("rowSpan");
                            rowspan1 = $(rt).attr("rowSpan")
                        }
                        rowspan = Number(rowspan) + 1;
                        rowspan1 = Number(rowspan1) + 1;
                        $(that).attr("rowSpan", rowspan);
                        $(rt).attr("rowSpan", rowspan);
                        $(gg).hide();
                        $(qq).hide();

                });
            });
        }
    });

//结果

或使用ligerUI的自带属性（自带的感觉不是很友好，不知道是兼容问题还是其它原因）

 mergeCell:null,       //合并表的列用法传入[0,1,2],索引0开始表示需要合并第一，第二，第三列
