【问题描述】:
我有下表。我需要根据产品对它们进行分组,并在设置 = 1 时增加组号,但如果新产品在下一行,则返回 1。我已经创建了一个索引。
| Index | Product | Set |
|---|---|---|
| 1 | Table | 0 |
| 2 | Table | 0 |
| 3 | Table | 1 |
| 4 | Table | 0 |
| 5 | Table | 0 |
| 6 | Table | 1 |
| 7 | Table | 0 |
| 8 | Table | 1 |
| 9 | Chair | 0 |
| 10 | Chair | 0 |
| 11 | Chair | 0 |
| 12 | Chair | 1 |
| 13 | Chair | 0 |
| 14 | Chair | 0 |
| 15 | Chair | 1 |
这是我想要的结果:
| Index | Product | Set | Group |
|---|---|---|---|
| 1 | Table | 0 | 1 |
| 2 | Table | 0 | 1 |
| 3 | Table | 1 | 1 |
| 4 | Table | 0 | 2 |
| 5 | Table | 0 | 2 |
| 6 | Table | 1 | 2 |
| 7 | Table | 0 | 3 |
| 8 | Table | 1 | 3 |
| 9 | Chair | 0 | 1 |
| 10 | Chair | 0 | 1 |
| 11 | Chair | 0 | 1 |
| 12 | Chair | 1 | 1 |
| 13 | Chair | 0 | 2 |
| 14 | Chair | 0 | 2 |
| 15 | Chair | 1 | 2 |
