用C++自定义数据透视表的全球化设置

可能的使用场景

有时你想根据需要自定义总计、子总计、总览、小计、多选项、列标签、行标签、空值的文本。Aspose.Cells for C++允许你自定义数据透视表的全球化设置，以应对这些场景。你还能使用此功能将标签更改为阿拉伯语、印地语、波兰语等其他语言。

自定义数据透视表的全球化设置

以下示例代码说明如何为 C++ 中的数据透视表自定义全球化设置。它创建一个派生自 PivotGlobalizationSettings 基类的类 CustomPivotTableGlobalizationSettings，并重写所有必要的方法。这些方法返回各种数据透视表元素的自定义文本。然后，代码将此实现分配给 WorkbookSettings.GetPivotSettings() 属性。示例加载一个 源 Excel 文件，刷新数据透视表并保存为 输出 PDF。下方截图显示了输出中的自定义标签。

示例代码

#include <iostream>
#include "Aspose.Cells.h"
