PivotTable.InGridDropZones (Excel)
This property is used to toggle in-grid drop zones for a PivotTable object. In some cases, it also affects the layout of the PivotTable.
When the InGridDropZones property is set to True, there are in-grid drop zones. When the property is set to False, there are no in-grid drop zones. The PivotTable layout also changes with this property.
