how to add header multi lines

[Liviu Lalescu]

You could use the teachers' comments and legend, but it is not exactly what you suggest. I will write down your suggestion.

[Volker Dirr]

You can do that if you use TiTiTo. The feature is implemented there.

fixed header for all teachers and students.....

[Volker Dirr]

You can add any html stuff before and also after the tables.
See
TiTiTo -> Timetables -> Additional Preface
and
TiTiTo -> Timetables -> Additional Postface
