How to repeat the header (or a modified header) of a multi-page table?

[tooremdrama]

@janekfleper

#set page(
  header: table(columns: (1fr, 1fr, 1fr), "My", "header", "table"),
  footer: table(columns: (1fr, 1fr, 1fr), "My", "footer", "table"),
)
#lorem(900)

This answer perfectly to my current need. I complicate myself alone

Thank you for all your answer, I discover a lot of thing that can be useful in future finally. ^^
