How to delete specific rows or columns in a sheet?

[DangYi4113]

Sorry, I recently started using this library. The functionality I want is to delete certain rows or columns—for example, deleting rows 5 to 10 (6 rows total), after which the original row 11 becomes row 5, row 12 becomes row 6, and so on. Alternatively, deleting column C would make the original column D become column C, column E become column D, etc. I couldn’t find such functions in xlsxworksheet.h or other files. The workaround I can think of is reading the entire sheet, manually adjusting it, and rewriting it to the file. Is there a better approach?
