golang excelize how to create page header for every page , as well as how to do the printer page setup
Looks like you are asking about this module: GitHub - qax-os/excelize: Go language library for reading and writing Microsoft Excel™ (XLAM / XLSM / XLSX / XLTM / XLTX) spreadsheets
According to the docs it looks like you use File.SetHeaderFooter to set a header for every page.
For printer page setup there is File.SetPageLayout, File.SetPageMargins, & their related options.
hope that helps!
