清除数据透视表中的筛选器

可能的使用场景

当你用已知数据创建数据透视表并想筛选数据透视表时,你需要学习并使用筛选器。它可以帮助你有效筛选出所需数据。通过使用Aspose.Cells for Java脚本的C++API,你可以对数据透视表中的字段值进行操作筛选。

如何在Excel中清除数据透视表中的筛选器

在 Excel 中清除数据透视表中的筛选,按照以下步骤操作:

  1. 选择要清除筛选的数据透视表。
  2. 单击数据透视表中要清除筛选的下拉箭头。
  3. 从下拉菜单中选择“清除筛选”。
  4. 如果您要清除数据透视表中的所有筛选,还可以在 Excel 的“数据透视表分析”选项卡上单击“清除筛选”按钮。

如何使用Aspose.Cells for Java脚本通过C++在数据透视表中清除筛选器

使用Aspose.Cells for Java脚本通过C++清除数据透视表中的筛选器。请查看以下示例代码。

  1. 设置数据并创建基于该数据的数据透视表。
  2. 在数据透视表的行字段上添加筛选。
  3. output XLSX 格式保存工作簿。执行示例代码后,将在工作表中添加带有 top10 筛选的数据透视表。
  4. 清除特定数据透视字段上的筛选。执行清除筛选的代码后,将清除特定数据透视字段上的筛选。请检查 output XLSX
