Excel - 匹配数据并写入另一列

Question

我正在寻找一些数据匹配以显示在第三位。 我有文件夹的列和第二列显示哪些用户可以访问该文件夹，那么：

Column1 Column2 
Folder1 User1 
Folder1 User2 
Folder2 User1 
Folder3 User1 

我有我想搜索（我做了基于掀起了“独一无二”列表中的用户列表的Column2）并且希望在Column2和Column3中找到匹配，将用户与相应的文件夹分隔开。它不一定是第3列，它甚至可以是另一个表，数据是第3列是我完成后唯一需要的数据。因此Column3看起来像：

User1|Folder1|Folder2|Folder3 
User2|Folder1 

这是否有意义？

感谢您提供任何帮助。 斯科特

Answer 1

采用芯片的UDF位于here并列入下面你可以再在你的靶细胞的地方下面的公式：

=TRIM(stringconcat(" | ",IF(B:B="User1",A:A,""))) 

这将输出与串联的所有文件夹“|” “User1”的分隔符。欢呼声中，
