# Adding Fields to a Pivot Table

Two important things to note when adding fields to a Pivot Table are Orientation and Position. Sometimes a developer may assume where a field is placed, so it's always clearer to explicitly define these parameters. These actions only affect the given Pivot Table, not the Pivot Cache.

Dim thisPivot As PivotTable
Dim ptSheet As Worksheet
Dim ptField As PivotField

Set ptSheet = ThisWorkbook.Sheets("SheetNameWithPivotTable")
Set thisPivot = ptSheet.PivotTables(1)

With thisPivot
    Set ptField = .PivotFields("Gender")
    ptField.Orientation = xlRowField
    ptField.Position = 1
    Set ptField = .PivotFields("LastName")
    ptField.Orientation = xlRowField
    ptField.Position = 2
    Set ptField = .PivotFields("ShirtSize")
    ptField.Orientation = xlColumnField
    ptField.Position = 1
    Set ptField = .AddDataField(.PivotFields("Cost"), "Sum of Cost", xlSum)
    .InGridDropZones = True
    .RowAxisLayout xlTabularRow
End With

# Creating a Pivot Table

One of the most powerful capabilities in Excel is the use of Pivot Tables to sort and analyze data. Using VBA to create and manipulate the Pivots is easier if you understand the relationship of Pivot Tables to Pivot Caches and how to reference and use the different parts of the Tables.

At its most basic, your source data is a Range area of data on a Worksheet. This data area MUST identify the data columns with a header row as the first row in the range. Once the Pivot Table is created, the user may view and change the source data at any time. However, changes may not be automatically or immediately reflected in the Pivot Table itself because there is an intermediate data storage structure called the Pivot Cache that is directly connected to the Pivot Table itself.

If multiple Pivot Tables are needed, based on the same source data, the Pivot Cache may be re-used as the internal data store for each of the Pivot Tables. This is a good practice because it saves memory and reduces the size of the Excel file for storage.

As an example, to create a Pivot Table based on the source data shown in the Figures above:

Sub test()
    Dim pt As PivotTable
    Set pt = CreatePivotTable(ThisWorkbook.Sheets("Sheet1").Range("A1:E15"))
End Sub

Function CreatePivotTable(ByRef srcData As Range) As PivotTable
    '--- creates a Pivot Table from the given source data and
    '    assumes that the first row contains valid header data
    '    for the columns
    Dim thisPivot As PivotTable
    Dim dataSheet As Worksheet
    Dim ptSheet As Worksheet
    Dim ptCache As PivotCache
    
    '--- the Pivot Cache must be created first...
    Set ptCache = ThisWorkbook.PivotCaches.Create(SourceType:=xlDatabase, _
                                                  SourceData:=srcData)
    '--- ... then use the Pivot Cache to create the Table
    Set ptSheet = ThisWorkbook.Sheets.Add
    Set thisPivot = ptCache.CreatePivotTable(TableDestination:=ptSheet.Range("A3"))
    Set CreatePivotTable = thisPivot
End Function

    # Formatting the Pivot Table Data

    This example changes/sets several formats in the data range area (DataBodyRange) of the given Pivot Table. All formattable parameters in a standard Range are available. Formatting the data only affects the Pivot Table itself, not the Pivot Cache.

    NOTE: the property is named TableStyle2 because the TableStyle property is not a member of the PivotTable's object properties.

    Dim thisPivot As PivotTable
Dim ptSheet As Worksheet
Dim ptField As PivotField

Set ptSheet = ThisWorkbook.Sheets("SheetNameWithPivotTable")
Set thisPivot = ptSheet.PivotTables(1)

With thisPivot
    .DataBodyRange.NumberFormat = "_($* #,##0.00_);_($* (#,##0.00);_($* "-"??_);_(@_)"
    .DataBodyRange.HorizontalAlignment = xlRight
    .ColumnRange.HorizontalAlignment = xlCenter
    .TableStyle2 = "PivotStyleMedium9"
End With
