Easyui 表格列数据合并！

//datagrid调用列子
onLoadSuccess: function (data) {
                $(".datagrid-header-row").css("text-align", "center");
                if (data.rows.length > 0) {
                    //调用mergeCellsByField()合并单元格
                    mergeCellsByField("grid", "c0003_stname,c0070_enterprise_name,c0007_name_pk");
                }
            }

//参数 tableID 要合并table的id
//参数 colList 要合并的列,用逗号分隔(例如："name,department,office");  ,这边写死为  ENT_NAME
function mergeCellsByField(tableID, colList) {
    var ColArray = colList.split(",");
    var tTable = $("#" + tableID);
    var TableRowCnts = tTable.datagrid("getRows").length;
    var tmpA;
    var tmpB;
    var PerTxt = "";
    var CurTxt = "";
    var alertStr = "";
    for (j = ColArray.length - 1; j >= 0; j--) {
        PerTxt = "";
        tmpA = 1;
        tmpB = 0;

        for (i = 0; i <= TableRowCnts; i++) {
            if (i == TableRowCnts) {
                CurTxt = "";
            }
            else {
                CurTxt = tTable.datagrid("getRows")[i][ColArray[j]];
            }
            if (PerTxt == CurTxt) {
                tmpA += 1;
            }
            else {
                tmpB += tmpA;

                tTable.datagrid("mergeCells", { //根据ColArray[j]进行合并
                    index: i - tmpA,
                    field: ColArray[j],
                    rowspan: tmpA,
                    colspan: null
                });

                tmpA = 1;
            }
            PerTxt = CurTxt;
        }
    }
};
