Thanks for the answers, but there is still something missing in order
to get it to work. Part of it seems to be connected to the python
parsing. E.g. the following translation of Eric's sh example doesn't
output correctly with python:
#+BEGIN_SRC python :results output
print """,A,B,C
0,0.628365,0.424279,0.619791
1,0.799666,0.527572,0.132928
2,0.837255,0.138906,0.408233
3,0.388080,0.146212,0.575346
"""
#+END_SRC
#+RESULTS:
: ,A,B,C
: 0,0.628365,0.424279,0.619791
: 1,0.799666,0.527572,0.132928
: 2,0.837255,0.138906,0.408233
: 3,0.388080,0.146212,0.575346
#+BEGIN_SRC python :results table
return """,A,B,C
0,0.628365,0.424279,0.619791
1,0.799666,0.527572,0.132928
2,0.837255,0.138906,0.408233
3,0.388080,0.146212,0.575346
"""
#+END_SRC
#+RESULTS:
| ,A,B,C\n\n0,0.628365,0.424279,0.619791\n\n1,0.799666,0.527572,0.132928\n\n2,0.837255,0.138906,0.408233\n\n3,0.388080,0.146212,0.575346

It seems that the only way to get a table from python is by outputting
a two dimensional python structure:
#+BEGIN_SRC python
return [[0,0.628365,0.424279,0.619791],
[1,0.799666,0.527572,0.132928]]
#+END_SRC
#+RESULTS:
| 0 | 0.628365 | 0.424279 | 0.619791 |
| 1 | 0.799666 | 0.527572 | 0.132928 |
This seems quite limiting....
Another related question is if there is any support for header tables?
I.e. instead of this:
| | A | B | C |
| 0 | 0.827817 | 0.664009 | 0.089161 |
| 1 | 0.170031 | 0.729214 | 0.110918 |
| 2 | 0.575918 | 0.863924 | 0.757536 |
| 3 | 0.682722 | 0.774445 | 0.992041 |
I want this:
| | A | B | C |
|---+----------+----------+----------|
| 0 | 0.827817 | 0.664009 | 0.089161 |
| 1 | 0.170031 | 0.729214 | 0.110918 |
| 2 | 0.575918 | 0.863924 | 0.757536 |
| 3 | 0.682722 | 0.774445 | 0.992041 |
I guess that if I start playing around with the python ob module, it
should be possible to get this working?
Regards,
Dov
