Not with the lazy quantifier +?: /.+?\|\}/ means "as few chars
as possible up to an "|}"; thus the match will stop at the
first "|}", and thus at most one table can participate in
each match. Contrast /.+\|\}/ without the ? which will
match everything up to the last "|}" in the string/file.
(Ignoring for the sake of uncluttering the /s modifier
necessary to have .+? or .+ match spans including newlines!)
