我有一个数据透视图，当前具有引用我表的数据源。
每周我都运行代码，并将新的一行数据附加到表的底部。
数据透视表确实会引用该表，因此每周都会收集一次此新数据，但是，我希望每周减少一周的时间，因此我拥有一年的数据。所以我想在行周围添加。
是否有必要将表格调整为仅包含价值几年的行？
这是我的示例数据：

更改数据透视表的源范围将非常棘手，因为Excel不允许在数据透视表中使用非连续的单元格。相反，您可以通过选择整个列来创建枢轴，以说明将来的所有条目。 然后可以操纵枢轴以显示变化的范围，如下面的代码所示。 希望对您有用。
编辑
下面更新了代码，从底部开始包含50（可以更改）。
Sub MovingPivot()
Dim ws As Worksheet
Dim dtTop As Date
Dim i As Integer, n As Long
Const NumWeeks = 50 'Change this to set weeks range
Set ws = ActiveSheet 'Set reference to your worksheet here
'reset the pivot filters
ws.PivotTables("Table1").PivotFields("Date").ClearAllFilters
'remove blank values
ws.PivotTables("Table1").PivotFields("Date").PivotItems("(blank)").Visible = False
'find the date entry in 50 places from bottom.
i = 0
For n = ws.PivotTables("Table1").RowRange.Count To 1 Step -1
If i = NumWeeks Then
dtTop = ws.PivotTables("Table1").RowRange.Cells(n).Value
Exit For
End If
i = i + 1
Next n
ws.PivotTables("Table1").PivotFields("Date").PivotFilters.Add2 Type:=xlAfterOrEqualTo, Value1:=Format(dtTop, "dd-mmm-yyyy")
End Sub

如果要继续使用数据透视图，则可以使用时间线切片器包括/排除数据。刷新数据后，您需要调整时间线或手动进行过滤。或编写VBA来设置过滤器。
也可以使用标准图表（而不是数据透视图）来实现不需要切片器的非vba版本。使用偏移功能创建命名范围，该功能仅捕获您感兴趣的数据行，然后将这些范围名称插入标准图表。当向表中添加新数据时，用于标准图表的命名范围也将被更新。
