如何按照下面的屏幕截图实现数据透视表中的重复所有项目，还需要知道如何在所有列中获取该下拉图标。现在下拉图标仅显示在第一列。 Apache POI 中可以实现重复所有项目吗？
下面是代码。
我得到的输出:
我需要的输出:
public class TestPivotTable

public static void main(String[] args) throws Exception

最佳答案
数据透视表的“重复所有项目标签”设置是在Office Open XML之后实现的。已发布。这就是为什么它不是其中的一部分。它使用特殊扩展XML来自 namespace x14 。但是apache poi只提供Office Open XML .
所以如果我们想使用扩展 XML来自 namespace x14 ，我们需要在低 XML 上这样做级别。
首先，我们需要将更新的数据透视表版本设置为 6 而不是 3。
然后我们需要设置<x14:pivotField fillDownLabels="1"/>对于每个 CTPivotField 。这是“重复所有项目标签”设置。

注意:我已删除 XSSFTable从您的代码创建，因为它是不必要的并且做得错误并导致损坏 Excel如果像您所做的那样完成，则归档。
