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);
