我有两张包含许多行和列的 Excel 工作表。表 1 是基线表，表 2 是新数据表。我想比较两个工作表并查看工作表 2 中缺少哪些数据以及工作表 2 中添加了哪些新数据。当在工作表 2 中添加/删除任何行时，这些行的值将不匹配。

作为第一步，我创建了一个宏来连接 Col A 到 E，并在两张纸上显示 Col H 中的结果。现在我需要在工作表 3 中创建一个宏，它将比较两个工作表中的 Col H，并将结果显示为缺失数据 (Sheet3:Col C) 和新数据 (Sheet3:Col D)。(Sheet3:Col A) 和 (Sheet3:Col B) 将分别是来自 Sheet 1 和 Sheet 2 的串联 COL H。我目前有一个宏，即使零件存在于表 1 中，它也会显示误报。

将连接的列作为键存储在Dictionary Object中。

Option Explicit

Sub MacroCompare()

    Const C = "~" ' concatenation character

    Dim wb As Workbook
    Dim ws1 As Worksheet, ws2 As Worksheet, ws3 As Worksheet
    Dim iLastRow As Long, iCompare As Long

    Set wb = ThisWorkbook
    Set ws1 = wb.Sheets(1) ' baseline
    Set ws2 = wb.Sheets(2) ' test

    Dim dict, k
    Set dict = CreateObject("Scripting.Dictionary")
    
    ' scan baseline build dictionary
    iLastRow = ws1.Cells(Rows.Count, "A").End(xlUp).Row
    For r = 2 To iLastRow
        ' concatenate
        ar = ws1.Cells(r, "A").Resize(1, 5) ' A to E
        k = ar(1, 1)
        For i = 2 To UBound(ar, 2)

            'ws2.Cells(r, "A").Interior.Color = vbGreen
            addCount = addCount + 1
        End If
    Next

    ' show deleted
    For Each k In dict
        r = dict(k)
        iCompare = iCompare + 1
        ws3.Cells(iCompare, "A") = k '"Row " & r

    Next
 
   ' result
    s = "added = " & addCount & vbCrLf & _

    MsgBox s, vbInformation

End Sub
