Request for adding API support for Pivot Tables.
GemBox.Spreadsheet supports Pivot Tables only through the preservation in XLSX files.

More information about GemBox.Spreadsheet's preservation can be found on the following link:
This feature request has been implemented and is available in the latest versions of GemBox.Spreadsheet.
