[Orgmode] [babel] passing tables to python source blocks

[Maurizio Vitale]

Hi,
    I get the following error when passing a table containing a line
separator (like mounts below). It looks like the table is first exported
to ASCII (and the horizontal line mapped to hline), but hline is not
known in python-land. Would it be possible to discard it instead?
Thanks,

        Maurizio
