Apache POI：如何设置数据透视表的显示布局？

Question

我尝试使用poi生成excel并在其中建立数据透视表。 像下面的代码。

这不是我想要的。 您可以在结果中看到。只有一个月带有过滤器图标。

，但是当您在数据透视表中选择一个单元格时，请选择设计选项卡。 选择“报告布局”，然后更改为以大纲形式显示 该过滤器将应用于month，group1和代码。

有什么方法可以使用poi来完成我之前描述的步骤吗？

Answer 1

关于数据透视表的大纲表单的问题，您需要在代码中进行的更改是：

不要不设置：

pivotTable.getCTPivotTableDefinition().getPivotFields().getPivotFieldArray(0).setOutline(false);

因为这是设置轮廓的错误位置。

代替：

...
pivotTable.getCTPivotTableDefinition().setCompact(false);
pivotTable.getCTPivotTableDefinition().setCompactData(false);
pivotTable.getCTPivotTableDefinition().setOutline(true); 
pivotTable.getCTPivotTableDefinition().setOutlineData(true);
...

这将从紧凑布局切换到轮廓布局。

但是对于我来说，您的其他XSSFTable代码导致Excel文件损坏，因为您是在工作表而非表中设置自动过滤器。我正在使用apache poi 4.1.0，打开Excel文件时，用于创建正在使用的表的代码会导致警告消息。然后Excel通过删除表来修复文件。不确定为什么XSSFTable绝对必要，但为了完整起见，使用apache poi 4.1.0可以正常工作的完整示例。
