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

[John Kitchin]

Here is another 'source block' solution, this time in python. You could so something  similar in elisp. Here I use the library of babel approach so you can call it wherever you want.

#+name: csv
| ID | Name         | Titel / Title | Vorname / First Name | Nachname / Surname | Institution           |
|  3 | Carol Carrot | Prof.         | Carol                | Carrot             | University of Veg     |
|  1 | Alice Apple  | Fr./Ms.       | Alice                | Apple              | Universität zum Apfel |
|  2 | Bob Birne    | Hr./Mr.       | Bob                  | Birne              | Pear University       |


See https://orgmode.org/worg/org-contrib/babel/library-of-babel.html

#+name: signature-table
#+BEGIN_SRC python  :var data="" :results value raw
results = [[surname, firstname, ""] for _, _, _, firstname, surname, _ in data[1:]]

sorted_results = sorted(results,key=lambda row: row[1])

sorted_results = [[i + 1] + result for i, result in enumerate(sorted_results)]

import tabulate
return tabulate.tabulate(sorted_results, ['#', 'Surname', 'First name', 'Signature'], tablefmt='orgtbl')
#+END_SRC



#+call: signature-table(data="">
#+RESULTS:
| # | Surname | First name | Signature |
|---+---------+------------+-----------|
| 1 | Apple   | Alice      |           |
| 2 | Birne   | Bob        |           |
| 3 | Carrot  | Carol      |           |

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
