比较行和报告差异Excel VBA

我一直在尝试使用下面的代码来比较两个Excel工作表，但是我无法让它完全按照我的需要运行。我需要逐行比较，并报告特定的差异，即使每张工作表上的数据行顺序不一定相同。代码根据数据在表中的物理存在方式报告所有差异。所以它显示了差异，但如果数据在每个表中按相同的顺序排列，它们实际上不会有差异。由于数据的性质，我不能先排序。希望这是有意义的。有人能告诉我需要什么样的改变才能得到我所需要的吗

在将要更新的工作表中，将每一行转换为字符串并保存到字典中。然后，在要更新的工作表中，遍历所有行，获取它们的字符串代表，并查看字典中是否存在该字符串代表。如果没有，则添加它们

下面是一个示例代码，它从行值中获取字符串

Sub getRowAsString()
    Dim cell As Object
    Dim sheet As Worksheet
    Dim str As String
    Dim arr() As Variant
    Dim arr2() As Variant
    Dim printCol As Integer

    Set sheet = ActiveSheet
    printCol = sheet.UsedRange.Columns.Count + 1

    For Each cell In sheet.UsedRange.Rows
        arr = cell.Value2
        ReDim arr2(LBound(arr, 2) To UBound(arr, 2))

        For i = LBound(arr, 2) To UBound(arr, 2)
            arr2(i) = arr(1, i)
        Next i

        str = Join(arr2, ", ")
        ActiveSheet.Cells(cell.Row, printCol).value = str
    Next cell
End Sub

下面是一个使用字典的示例：

Sub createDictionary()
    Dim dict As Object
    Set dict = CreateObject("Scripting.Dictionary")

    Key = "hello"
    value = "world"
    dict.Add Key, value

    MsgBox "key exists: " & dict.exists(Key) & vbNewLine & "value: " & dict(Key)
End Sub

如果行的字符串表示太大，可以将其哈希值保存到字典中，以使其更易于管理。是一篇提供VBA代码对字符串进行散列的文章

如果没有某种“键”来标识工作表之间的“相同”数据行，则无法实际执行此操作。是否有某些列或列的组合在每条记录中应该是唯一的？^如果要查找行中的差异，如何才能识别该行？如果行不相同，顺序也不相同，那么是什么？您需要某种方式将sheet1中的行映射到Sheet2Tanks中的行，以便发表评论。所有行都是唯一的，所以这就是为什么我认为这是可能的。我需要找出那些不匹配的，并在可能的情况下强调原因。示例数据，A列、B列和E列的组合应该是唯一的。感谢您的回复，我将尝试一下。
