Re: [O] Import CSV file, remove columns, print table

[Loris Bennett]

Hi John,

Thanks - that's a nicely compact solution, albeit in the category
'source block' and in a language I'm not very skilled at :-)

I realise that I have slightly misstated the problem.  The ID in the
imported CSV is just a key from the database - I don't need it on the
list of participants.  However, it would be nice to number the
participants, who are sorted by surname.

How would I insert a column which just numbers the row?

Cheers,

Loris
