搜索字符串並從另一列返回多個值

Question

Return Lookup Array Lookup Value Expected Output 
A 2 1 NA 
B 2 2 A, B, C 
C 2 3 D,E 
D 3 4 F, G 
E 3 5 NA 
F 4 6 NA 
G 4 7 NA 

這就是表的樣子。第四列是我期望的返回值。我在第2列使用第3列查找值，輸出是第4欄

由於需要在同一小區內返回多個值，你可能會需要一些VBA這裏：

Function doLookup(lookupValue As String) As String 
    Dim searchRange As Range 
    Dim searchCell As Range 
    Dim searchValue As String 

    'What range are we searching here? 
    Set searchRange = Sheet1.Range("B1:B" & Sheet1.Range("B" & Sheet1.Rows.Count).End(xlUp).Row()) 

    'Loop through each cell in the range 
    For Each searchCell In searchRange 

     searchValue = searchCell.Value 

     'If we find a match... 
     If searchValue = lookupValue Then 

      'If this is not the first thing in the list, then add a comma 
      If doLookup <> "" Then doLookup = doLookup & "," 

      'Add the thing we found 
      doLookup = doLookup & searchCell.Offset(0, -1).Value 
     End If 
    Next searchCell 
End Function 

堅持這個在一個新的模塊，然後在D1使用公式=DoLookup(C1)它應該吐出你在找什麼。如果名單非常大，那麼不要指望這太活潑了。
