Re: MWE for building a table using Lua

[Bastien DUMONT <bastien.dumont-VwIFZPTo/vqsTnJN9+BGXg@public.gmane.org>]

The constructors don't take tables as their argument, but discrete values. I have not found the definition of the constructors in the official documentation, but you can look into this filter to see how they work: https://github.com/pandoc/lua-filters/blob/master/list-table/list-table.lua
