Request for adding API support for Autofilters.
GemBox.Spreadsheet supports Autofilters only through the preservation in XLSX files.
This means that if applied some auto filters in our XLSX file we can load our file with a GemBox.Spreadhsheet, make any required modifications, and save it back to an XLSX format. The output file will contain auto filters from the original input file, but they are not directly supported by GemBox.Spreadsheet API.
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.
