我正在自动化在 Excel 中创建数据透视表的过程。我遇到的问题是,我使用宏创建的数据透视表比我手动创建的数据透视表大得多。两个数据透视表看起来相同,但文件大小有很大差异。
如上图所示,我的宏创建的大约是原来的 6 倍大!我怀疑这是我在创建数据透视表时缓存数据的方式。因此,这是我用来创建数据透视表的通用代码。
Sub pivottable1()
Dim PSheet As Worksheet, DSheet As Worksheet
Dim PCache As PivotCache
Dim PTable As PivotTable
Dim PField As PivotField
Dim PRange As Range
Dim LastRow As Long
Dim LastCol As Long
Dim PvtTable As PivotTable
Dim SheetName As String
Dim PTName As String
SheetName = "MySheetName1"
PTName = "PivotTable1"
On Error Resume Next
Application.DisplayAlerts = False
Worksheets(SheetName).Delete
Sheets.Add After:=ActiveSheet
ActiveSheet.Name = SheetName
Application.DisplayAlerts = True
Set PSheet = Worksheets(SheetName)
Set DSheet = Worksheets(1)
LastRow = DSheet.Cells(Rows.Count, 1).End(xlUp).Row
LastCol = DSheet.Cells(1, Columns.Count).End(xlToLeft).Column
Set PRange = DSheet.Cells(1, 1).Resize(LastRow, LastCol)
Set PCache = ActiveWorkbook.PivotCaches.Create _
(SourceType:=xlDatabase, SourceData:=PRange). _
CreatePivotTable(TableDestination:=PSheet.Cells(4, 1), _
TABLENAME:=PTName)
Set PTable = PCache.CreatePivotTable _
(TableDestination:=PSheet.Cells(1, 1), TABLENAME:=PTName)
Sheets(SheetName).Select
Set PvtTable = ActiveSheet.PivotTables(PTName)
'Rows
With PvtTable.PivotFields("TypeCol")
.Orientation = xlRowField
.Position = 1
End With
With PvtTable.PivotFields("NameCol")
.Orientation = xlRowField
.Position = 2
End With
'Columns
With PvtTable.PivotFields("CategoryCol")
.Orientation = xlColumnField
.Position = 1
End With
'Values
PvtTable.AddDataField PvtTable.PivotFields("Values1"), "Value Balance", xlSum
PvtTable.AddDataField PvtTable.PivotFields("Values2"), "Value 2 Count", xlCount
With PvtTable
.PivotFields("TypeCol").ShowDetail = False
.TableRange1.Font.Size = 10
.ColumnRange.HorizontalAlignment = xlCenter
.ColumnRange.VerticalAlignment = xlTop
.ColumnRange.WrapText = True
.ColumnRange.Columns.AutoFit
.ColumnRange.EntireRow.AutoFit
.RowAxisLayout xlTabularRow
.ShowTableStyleRowStripes = True
.PivotFields("TypeCol").AutoSort xlDescending, "Value Balance" 'Sort descdending order
.PivotFields("NameCol").AutoSort xlDescending, "Value Balance"
End With
'Change Data field (Values) number format to have thousand seperator and 0 decimal places.
For Each PField In PvtTable.DataFields
PField.NumberFormat = "#,##0"
Next PField
End Sub
这就是我创建 6 个不同的数据透视表的方法,这些表都使用位于同一工作簿中且位于该工作簿的第一个工作表中的相同数据源。因此,例如我的第二个数据透视表宏代码将如下所示。
Sub pivottable2()
Dim PSheet As Worksheet, DSheet As Worksheet
Dim PCache As PivotCache
Dim PTable As PivotTable
Dim PField As PivotField
Dim PRange As Range
Dim LastRow As Long
Dim LastCol As Long
Dim PvtTable As PivotTable
Dim SheetName As String
Dim PTName As String
SheetName = "MySheetName2"
PTName = "PivotTable2"
On Error Resume Next
Application.DisplayAlerts = False
Worksheets(SheetName).Delete
Sheets.Add After:=ActiveSheet
ActiveSheet.Name = SheetName
Application.DisplayAlerts = True
Set PSheet = Worksheets(SheetName)
Set DSheet = Worksheets(1)
LastRow = DSheet.Cells(Rows.Count, 1).End(xlUp).Row
LastCol = DSheet.Cells(1, Columns.Count).End(xlToLeft).Column
Set PRange = DSheet.Cells(1, 1).Resize(LastRow, LastCol)
Set PCache = ActiveWorkbook.PivotCaches.Create _
(SourceType:=xlDatabase, SourceData:=PRange). _
CreatePivotTable(TableDestination:=PSheet.Cells(4, 1), _
TABLENAME:=PTName)
Set PTable = PCache.CreatePivotTable _
(TableDestination:=PSheet.Cells(1, 1), TABLENAME:=PTName)
Sheets(SheetName).Select
Set PvtTable = ActiveSheet.PivotTables(PTName)
'Rows
With PvtTable.PivotFields("ManagerCol")
.Orientation = xlRowField
.Position = 1
End With
With PvtTable.PivotFields("IDCol")
.Orientation = xlRowField
.Position = 2
End With
'Columns
With PvtTable.PivotFields("CategoryCol")
.Orientation = xlColumnField
.Position = 1
End With
'Values
PvtTable.AddDataField PvtTable.PivotFields("Values1"), "Value Balance", xlSum
End Sub
我更改的只是宏名称、工作表名称、数据透视表名称以及数据透视表的输入行/列/数据值。
我希望实现的是将宏创建的数据透视表的文件大小减小到与我手动创建的文件大小类似。
如果大家还有什么想了解的,欢迎评论。我将对问题进行编辑并分别添加详细信息。
最佳答案
您可以对多个数据透视表使用相同的数据透视缓存(假设它们基于相同的源数据)。
未经测试:
'creates and returns a shared pivotcache object
Function GetPivotCache() As PivotCache
Static pc As PivotCache 'static variables retain their value between calls
Dim pRange As Range
If pc Is Nothing Then 'create if not yet created
Set prRange = Worksheets(1).Range("A1").CurrentRegion
Set pc = ActiveWorkbook.PivotCaches.Create _
(SourceType:=xlDatabase, SourceData:=pRange)
End If
Set GetPivotCache = pc
End Function
Sub pivottable1()
'...
'...
Set PSheet = Worksheets(SheetName)
Set PCache = GetPivotCache() '<<< will be created if needed
Set PTable = PCache.CreatePivotTable _
(TableDestination:=PSheet.Cells(1, 1), TableName:=PTName)
'...
'...
End Sub
