Dear Christophe,
I am currently unaware of a column limit... and if there is one, it
would cause out-of-memory problems rather than this error message.
I would suggest that there is
a) an unexpectedly formed column in your table or
b) a bug in the processing code which occurs only for the particular
table or
c) encoding problems when parsing column names.
Since the problem appears already in line 1, I would suggest to look for
encoding problems in column names.
Perhaps you have a unicode character which causes TeX to bail out? Note
that pgfplotstable needs to process the input file
in a different way than inputenc. If that is really the cause, you may
want to file a bug to sourceforge (preferably with a minimal example)
and replace the offending character. You can still view it in the output
using the 'column name' style option.
Does this help?
Best regards
Christian
