row_group_as_column = TRUE + 2 group variables

[olivroy]

Summary

I tried a lot of things, but I am now missing a bit of context.

This fixes only the following case:

mtcars |>
  group_by(vs, cyl) |> 
  gt(row_group_as_column = TRUE)

Related GitHub Issues and PRs

• Ref: Addresses tab_row_group with row_group_as_column = TRUE yields sprintf error (read comments) #1552 (comment) (not the other issues)

I ended up reverting the other commits because I am not getting it right.

for the original issue, it is a problem that the stub is not correctly initialized when row_group_as_column = TRUE + no row groups at the beginning.

and tab_row_group() doesn't behave well
