Microsoft VBA Excel 去重+自动化配对信息

问题场景

A列数据中存在很多特别的情况：

1. 中间分隔符为“/”，但是分隔符前后可能存在空格
2. 一个编号可能出现多次，例如示例中6003出现了5次
3. 可能为空，虽然节选的这部分没出现这种情况

B和C列数据中，会出现空格。

A	B	C
6003	AAA	L7
6003/ 6007/6001	AA	L6
6000/6003/6009	A	L1
6000 / 6003	AA	L8
6003		L9

现在需要在新的Sheet中对原先的Sheet有以下操作：

1. 从不重复的提取出所有编号，例如该节选数据结果是6003、6007、6001、6000、6009
2. 对于提取的编号给予最后一次出现的行号，例如1中对应结果是5，2，2，4，3
3. 根据编号最后一次出现的行号提取B和C的信息，如果不为空则填入想同行的B和C列的信息，如果为空则寻找上一次出现的内容，例如最后一次6003为空，则找到上一次是第4行，输出AA

根据以上信息，示例数据的结果应该是：

A	B	C
6003	AA	L9
6007	AA	L6
6001	AA	L6
6000	AA	L8
6009	A	L1

---

代码描述

1. 分析和提取每个单元格中的编号。
2. 记录每个编号最后出现的行号以及对应的B和C列数据。
3. 填充新Sheet中的数据，如果B或C列为空，则查找之前的非空数据。
