问一下 easyUI treegrid 在节点下面追加一个节点 效果如图 出不来啊

Question

父节点变成了文件夹的图标 但是新增的节点没有出来

   if (editingId != undefined){  
                $('#tg').treegrid('select', editingId);  
                return;  
            }  
            var rows = $('#tg').treegrid('getChildren');  
            editingId = 40;  
            var row = null;  
            var _data = {"id":editingId,"code":"","orgname":"","price":""};  
            var _parentId = 0;  
            var row = $('#tg').treegrid('getSelected');  
            if (row){  
                $('#tg').treegrid('expand',row.id);  
                _parentId = row.id;  
            }else{  
                var root = $('#tg').treegrid('getRoot');  
                _parentId = null;  
            }  
            $('#tg').treegrid('append',{  
                parent: _parentId,   
                data: [_data]  
            });
