bootstrap Table实现合并相同行

 var table = $("#table"); // 初始化表格    table.bootstrapTable({     url: $.fn.bootstrapTable.defaults.extend.index_url,     pk: 'id',     sortName: 'update_time',     search: false,     toolbar: '#toolbar',     commonSearch: true,     pageSize : 12,     searchFormVisible: true,     queryParams: function (params) {      //这里可以追加搜索条件      var filter = JSON.parse(params.filter);      var op = JSON.parse(params.op);      //这里可以动态赋值，比如从URL中获取admin_id的值，filter.admin_id=Fast.api.query('admin_id');      // filter.admin_id = 1;      if(filter.is_bujiao=='是')       filter.is_bujiao=1      if(filter.is_bujiao=='否')       filter.is_bujiao=0      op.username = "like";      params.filter = JSON.stringify(filter);      params.op = JSON.stringify(op);      return params;     },     columns: [      [       {field: 'total_order_id', title: '总订单号',sortable: true,width: "150px",formatter: Table.api.formatter.search}      ]     ],          onLoadSuccess: function (data) {      mergeCells(data, "total_order_id", $("#table"));     },    }); // 为表格绑定事件Table.api.bindevent(table);
