I think this new recipe you propose works fine, although I haven't done a thorough test yet. In principle, it shouldn't be a problem. By the way, now I remember that the package verse adds a series of extra arguments to \\ (p. 6 in the documentation: https://www.ctan.org/pkg/verse). As a user, the only way I can think of to add arguments instead of [0pt] or \empty is by using a small export filter to act on the final output. Perhaps putting something like !!new-argument!! on the affected row/verse/line to guide the filter. > As to tabulararray, I still consider it as an experimental package. > Perhaps I will install a more modern container.

Keep in mind that tabularray is a latex3 package and, in principle, everything that is latex3 is here to stay. Certainly, it is a blessing compared to the classic tabular environments, because it is tremendously versatile. That is why it already has a significant number of users: https://tex.stackexchange.com/questions/tagged/tabularray And Org already provides what is necessary to use its syntax. I've had a first look at tabularray.sty, but I'm not familiar enough with the new LaTeX 3 syntax and, frankly, I'm lost... I've tried all the packages involved in tables that I can think of (longtable, siunitx, tabularx, booktabs, array, and I don't know if I forgot any) and in all of them the \empty solution works fine. It seems that tabularray is the black sheep here. > For a while I have the following question. Is \\{} have the same > effect on tabularray parser as \\\empty? Throw an error before \hline.
