将E列姓名中不包含A列姓名的全部列出：

方法一：
Sub shu1()
    '查找两列不相通内容
    Dim arr1 As Variant, arr2 As Variant
    Dim x As Long
    Dim y As Long
    With WorksheetFunction
        x = .CountA(Range("a10:a1000")) + 9
        y = .CountA(Range("e10:e1000")) + 9
        arr1 = .Transpose(Range("a10:a" & x).Value)
        arr2 = .Transpose(Range("e10:e" & y).Value)
    End With
    For i = 1 To UBound(arr1)
      arr2 = Filter(arr2, arr1(i), False, 1)

    Next i
    MsgBox "E列独有项为：" & Chr(10) & Join(arr2, ",")
End Sub

方法二：
Sub shu2()
    Dim d As Object, arr, i%, tem As String
    Set d = CreateObject("scripting.dictionary")
    With Sheets("sheet1")
        arr = .Range("a10", .[a65536].End(3))
        For i = 1 To UBound(arr)
            d(arr(i, 1)) = ""
        Next
        arr = .Range("e10", .[e65536].End(3))
        For i = 1 To UBound(arr)
            If d.exists(arr(i, 1)) = False Then
                tem = tem & Chr(10) & arr(i, 1)
            End If
        Next
    End With
    MsgBox "两列不相通项为：" & tem
End Sub
