从工作表中删除数据透视表

Aspose.Cells for JavaScript通过C++提供一种从工作表中删除或移除数据透视表的功能。您可以使用数据透视表对象或数据透视表位置删除。请使用Worksheet.pivotTables.remove(pivotTable)方法通过数据透视表对象删除，使用Worksheet.pivotTables.removeAt(index, keepData)方法通过数据透视表在集合中的位置删除。

如何使用Aspose.Cells for JavaScript通过C++删除工作表中的数据透视表

以下示例代码从工作表中删除了两个数据透视表。首先使用Worksheet.pivotTables.remove(pivotTable)方法移除数据透视表，然后使用Worksheet.pivotTables.removeAt(index, keepData)方法移除数据透视表。
