Aspose.Cells for JavaScript通过C++提供了PivotTable.cellByDisplayName(string)方法，可以使用该方法通过显示名称访问数据透视字段的单元格对象。当你想要突出显示或格式化数据透视字段标题时，这个方法非常有用。本文介绍了如何通过显示名称检索数据字段的单元格对象，然后进行格式设置。
如何通过数据透视表的PivotField的DisplayName获取Cell对象
以下代码访问工作表的第一个透视表，然后通过透视表的第二个数据字段的显示名称获取单元格。然后将单元格的填充颜色和字体颜色分别更改为浅蓝色和黑色。下面的屏幕截图显示了代码执行之前和之后透视表的外观。
