我有一张这样的桌子:
+------+-------+
|ID | value |
+------+-------+
| 1 | 150 |
| 2 | |
| 3 | |
| 4 | |
| 5 | 530 |
| 6 | 950 |
| 7 | 651 |
+-------+------+
我想复制最后 3 个值,最后我的表格将如下所示:
+------+-------+
|ID | value |
+------+-------+
| 1 | 150 |
| 2 | 530 |
| 3 | 950 |
| 4 | 651 |
| 5 | 530 |
| 6 | 950 |
| 7 | 651 |
+-------+------+
是否可以?
