Thanks for the reply, What I actually mean is that I use Spire.Spreadsheet to load a existed Excel file(xlsx) which created by MS Excel 2010 with Filter buttons in it, but all the Filter buttons are missed when the file is loaded.
Anyway, I use Spire.xls to build Filter button by line "sheet.AutoFilters.Range = sheet.Range["B3:AA23"];", it works in Spire.Spreadsheet.
