To expand on my answer: \\{} and \\\empty, before \hline, throw the same
error:
------------------------------
ERROR: Misplaced \noalign.
--- TeX said ---
\hline ->\noalign
{\ifnum 0=`}\fi \hrule \@height \arrayrulewidth \futurelet...
l.17 \end
{tblr}
--- HELP ---

I expect to see \noalign only after the \cr of
an alignment. Proceed, and I'll ignore this case.
