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);
