如何根据列表创建新工作表？

Question

我正在尝试根据另一个名为 GroupFileNames 的工作表中的组名列表为 sheet10 中找到的每个组创建新工作簿。

为了更轻松地进行故障排除，当前代码会创建新工作表而不是工作簿。我已经有了创建工作簿所需的代码。

我的问题是我的代码不会遍历组名列表。它为第一组 (ABC Corp) 创建一个工作表并复制其相应的数据，但它从不为下一个组 (XYZ Corp) 创建工作表。

我尝试了使用 Do Until、For Each 等不同的循环方式。

Sub CreateWkBookByGroupName()
    
    
    Dim Transaction() As Variant
    Dim GroupNameTransactions() As Variant
    Dim TransactionCounter As Long
    Dim GpnTransactionCounter As Long
    Dim Counter As Long
    Dim i As Integer
    Dim gfn As Worksheet
    Set gfn = ThisWorkbook.Sheets("GroupFileNames")
    Dim groupName As String
    
    
    i = 1
    groupName = gfn.Range("A" & i)
    
    'Store entire database in the Transaction array
    Transaction = Range("A1").CurrentRegion
    'Starting in the i row of the database loop through each transaction
    
    For TransactionCounter = i To UBound(Transaction, 1)
       
        'If the thirteenth column contains a value equal to groupName...
        If Transaction(TransactionCounter, 13) = groupName Then
            '...increase the GpnTransactionCounter by 1
            GpnTransactionCounter = GpnTransactionCounter + 1
            
            'Redimension the GroupNameTransaction array with each instance _
            of a GroupName transaction.
            ReDim Preserve _
              GroupNameTransactions(1 To 13, 1 To GpnTransactionCounter)
            'Start a counter to populate the GroupNameTransactions array
            For Counter = 1 To 13
                'The GroupNameTransactions array equals the current transaction
                GroupNameTransactions(Counter, GpnTransactionCounter) _
                  = Transaction(TransactionCounter, Counter)
            Next Counter
        End If
    Next TransactionCounter
    'Add a new sheet
    Worksheets.Add
    'Add the headings in the first row of the Transactions array
    Range("A1:M1") = Transaction
    'Transpose the GroupNameTransaction array onto the new sheet
    Range("A2", Range("A2").Offset(GpnTransactionCounter - 1, 12)) _
    = Application.Transpose(GroupNameTransactions)
    'Autofit columns
    Columns.AutoFit
    
End Sub

此数据应生成两个新工作表，一个用于 ABC Corp，另一个用于 XYZ Corp。每个新工作表都应包含属于其组的所有列。

这是我的代码用来与 Sheet10 上的组名进行比较的组名列表。

如果您确实需要创建作为分组数据子集的新工作表，那么嵌套脚本字典是一种有用的数据结构。

Option Explicit

    Dim myGroup As Variant

    For Each myGroup In myTransactionsGroupedByName
    
        With myTransactionsGroupedByName
        
            Set myWS = CreateSheetForGroupName(.Item(myGroup))
            myWS.Name = myGroup

    Static myHeadingRow As Excel.Range
    
    If myHeadingRow Is Nothing Then
