easyui的datagridt合并单元格

easyUI的合并单元格指合并行和合并列的单元格两种，这次我把这两种合并写到一起，首先说一下我所使用的环境
easyUI 版本1.5
使用的java后台使用springboot
看代码之前先看下效果图：

顶部合并单元格的代码，本菜鸟是采用后台写的，直接在页面写应该也可以，只是这里没做过多测试，有兴趣的小伙伴可以测试一下

		ActionResult ar = ActionResult.New();//这个是我借鉴别人的，看不懂可以滤过，对合并单元格没用
        List>> list = New.list();//这种创建对象的也是借鉴别人的，跟普通的new  treemap是一样的
        List> totalColumnList = New.list();
        Map totalColumnMap = null;

        int page = mapBean.getIntValue("page",0);
        int size = mapBean.getIntValue("size",20);

        //PagedData> tableDataList = productService.tableColumnsList(page,size);
        //这是表格的数据
        List> totalDataList = New.list();
        totalColumnMap = New.map();
        totalColumnMap.put("card_name","123");
        totalColumnMap.put("mobile","13614781236");
        totalColumnMap.put("a","56");
        totalColumnMap.put("b","23");
        totalColumnMap.put("v","33");
        totalDataList.add(totalColumnMap);

        totalColumnMap = New.map();
        totalColumnMap.put("card_name","123");
        totalColumnMap.put("mobile","13614781236");
        totalColumnMap.put("a","56");
        totalColumnMap.put("b","23");
        totalColumnMap.put("v","33");
        totalDataList.add(totalColumnMap);

        totalColumnMap = New.map();
        totalColumnMap.put("card_name","123");
        totalColumnMap.put("mobile","13614781236");
        totalColumnMap.put("a","56");
        totalColumnMap.put("b","23");
        totalColumnMap.put("v","33");
        totalDataList.add(totalColumnMap);

        totalColumnMap = New.map();

这是前台easyUI的代码，左侧合并单元格的代码是在页面的onLoadSuccess方法里写的，这种左侧合并行的方法有一定要求，就是从数据库查询的需要合并行的数据必须放到一起，如果有分开的，就失去了左侧合并单元格的意义（会出现同一种类型的多次合并的现象）
