Oh, and of course you need a \bTABLEhead, otherwise there’s nothing to
repeat.
That means AFAIK, the header can’t be part of the CSV, using this
simple module.
I tried to put the header into the before part of setupseparatedlist,
but this does not work. I also fear that I cannot do it with this
module. Are there other means to build a table from csv?
ConTeXt has a better parser for csv files since many years (which is
used by the already mentioned handlecsv module) but there is no TeX
interface for it.
The example below shows how the parser can be used to store csv data in
a Lua table, you can even split of the first line of data to use it as
header etc.
Afterwards you can use a loop to create a TeX table out of the stored
Lua table.
