终于让代码工作了。使用 PivotTableWizard 而不是添加/创建数据透视缓存。
下面是我的代码。还找到了一个函数 .UsedRange 用于选择使用的范围
Public Sub CountingRows()
Dim ws As Worksheet
Dim SheetName As String 'data sheet name
Dim TotalRows As Integer 'counts total number of rows
Dim TotalColumns As Integer 'sets total number of columns
Dim Counter As Integer 'Counter to start the loop
Dim wsPivot As Worksheet
Dim CreatePt As PivotTable 'creates using pivot table wizard
Dim CurrentViewPt As PivotTable
Dim PRange As Range
Dim PTCache As PivotCache
Dim PF As PivotField
'Deleting sheet if it already exists
   For Each ws In ThisWorkbook.Worksheets
   If ws.Name = "PivotTest1" Then
     ws.Delete
    End If
    Next
'Setting sheet names
SheetName = "Sheet 1" 'storing sheet name which will be default
 Set ws = Worksheets(SheetName)
Sheets.Add.Name = "PivotTest1"
 Set wsPivot = Worksheets("PivotTest1")
wsPivot.Select 'Activating worksheet
 'Delete any prior pivot tables
On Error Resume Next
For Each CurrentViewPt In wsPivot.PivotTables
    CurrentViewPt.TableRange2.Clear
Next CurrentViewPt
'Defining pivot table cache
 ws.Select
TotalColumns = ws.Cells(1, Columns.Count).End(xlToLeft).Column 'Counting total columns
TotalRows = ws.Range("A:A").Cells.SpecialCells(xlCellTypeConstants).Count 'Counting total rows
Set PRange = ws.UsedRange 'found a new function to use do not need to use above fields, but keeping them just incase
'Set PRange = ws.Cells(1, 1).Resize(TotalRows, TotalColumns)<<<Not sure if it works>>>
wsPivot.Select
 Set PTCache = ActiveWorkbook.PivotCaches.Create(SourceType:=xlDatabase, SourceData:=PRange)
'Create the Pivot Table
 Set CreatePt = wsPivot.PivotTableWizard(SourceType:=xlDatabase, SourceData:=PRange, TableDestination:=wsPivot.Range("B4"), TableName:="CurrentNBI")
 Set CurrentViewPt = wsPivot.PivotTables("CurrentNBI")
'**** Define the layout of the pivot table****
 With CurrentViewPt.PivotFields("NBI_CODE")
    .Orientation = xlRowField
    .Position = 1
  End With
   With CurrentViewPt.PivotFields("CREATION_DATE")
   .Orientation = xlRowField
   .Position = 2
   End With
   With CurrentViewPt.PivotFields("BUSINESS_AREA")
