我有2个问题...
我有 3 张桌子。tbl_target_cities、lib_cities 和 lib_provinces。
通过遵循视频教程，我能够将 tbl_target_cities 中的数据显示到 gridview 并将其连接到 lib_cities。
除了来自关系的 CITY/MUNICIPALITY 列之外，gridview 中的排序非常有效。
问题 1：如何更正 CITY/MUNICIPALITY 列的排序？
问题2：如何添加带有搜索框和功能排序功能的省份列？
tbl_target_cities
+-------------------+-----------------------+
| Field | Type |
+-------------------+-----------------------+
| id | int(11) |
| city_code | varchar(20) |
| kc_classification | varchar(100) |
| cluster | enum('1','2','3','4') |
| grouping | int(11) |
| priority | varchar(100) |
| launch_year | int(11) |
+-------------------+-----------------------+
lib_cities
+---------------+--------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+---------------+--------------+------+-----+---------+-------+
| city_code | char(9) | NO | PRI | | |
| city_name | varchar(100) | NO | MUL | NULL | |
| prov_code | char(9) | NO | MUL | NULL | |
| is_Urban | tinyint(1) | YES | | 0 | |
| locked | tinyint(1) | YES | | 0 | |
| app_target_hh | int(5) | YES | | NULL | |

lib_provinces
