Hello,
I discovered a problem on the converter mediawiki to gfm in table

Pandoc version (MacOS X)

pandoc 3.6
Features: +server +lua
Scripting engine: Lua 5.4

Source mediawiki

Mediawiki result

I run this command to transform my mediawiki file to a md file
pandoc -f mediawiki -t gfm ./test.mediawiki -o ./gfm-file.md

The error result is the following

Error at "./test.mediawiki" (line 13, column 1):
unexpected '!'

^

The generation works if I remove the + before the 0
