Excel：使用A和B之间的差异填充C列

Question

我在2个包含STRING值列的工作表（WS1和WS2）中有2列：A和B. 我想填写第三列＆＃34; C＆＃34;在第三个工作表（WS3）中有差异。

简单地说，我想用WS1中的项目名称填充WS3：C列：A但不在WS2中：B。

Answer 1

You could actually do quite simply:

The formula in column C is

=IF(COUNTIF($B$1:$B$10,A1),"",A1)

Here is a VBA alternative:

Option Explicit

Sub DisplayUnique()
    Dim output As Range, r As Range
    Dim dict As Object

    Set dict = CreateObject("Scripting.Dictionary")

    Set output = ThisWorkbook.Worksheets("Sheet1").Range("C1")

    For Each r In ThisWorkbook.Worksheets("Sheet1").Range("A1:A10")
        If ThisWorkbook.Worksheets("Sheet1").Range("B1:B10").Find(r.Value, , , xlWhole) Is Nothing Then
            If Not dict.exists(r.Value) Then dict.Add r.Value, r.Value
        End If
    Next r

    output.Resize(dict.Count, 1).Value = Application.Transpose(dict.keys)
End Sub
