可能的使用场景
有时您可能想根据需求自定义数据透视总计、小计、总计、所有项目、多项、列标签、行标签、空值文本。Aspose.Cells for JavaScript通过C++允许您自定义数据透视表的全球化设置来应对这些场景。您还可以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
以下示例代码说明了如何为数据透视表自定义全球化设置。它创建了一个继承自 PivotGlobalizationSettings 基类的 CustomPivotTableGlobalizationSettings 类，并重写了所有必要的方法。这些方法返回自定义的 Pivot Total、Sub Total、Grand Total、All Items、Multiple Items、Column Labels、Row Labels、Blank Values 的文本。然后将该类的对象分配给 WorkbookSettings.pivotSettings 属性。该代码加载包含数据透视表的源Excel文件（40468488.xlsx），刷新并计算其数据，然后保存为输出PDF（40468487.pdf）。以下截图显示了示例代码对输出PDF的效果。可以看到，数据透视表的不同部分现在返回了由 PivotGlobalizationSettings 类的重写方法所定制的文本。
