在数据透视表中处理数据字段的数据显示格式

Aspose.Cells for JavaScript通过C++支持所有DataField的数据展示格式。

“从最小到最大的排名”和“从最大到最小的排名”显示格式选项

ASpose.Cells提供了设置数据透视字段显示格式选项的功能。为此，API提供了PivotShowValuesSetting.calculationType属性。为了从最大到最小排名，您可以将PivotShowValuesSetting.calculationType属性设置为PivotFieldDataDisplayFormat.RankLargestToSmallest。以下代码片段演示了设置显示格式选项。
