Subject: Re: getting an hline in a python generated table

A simpler solution is to just use None, which gets automatically converted
to an hline by org-babel:

#+BEGIN_SRC python :return mytable
  NROWS, NCOLS = 6, 4
  mytable = []
  mytable.append(['A', 'B', 'C', 'D'])  # Table header
  mytable.append(None)                  # hline
  for irow in range(NROWS):
      mytable.append([icol**irow for icol in range(NCOLS)])
  mytable.append(None)                  # hline
#+END_SRC

#+RESULTS:
| A | B |  C |   D |
|---+---+----+-----|
| 1 | 1 |  1 |   1 |
| 0 | 1 |  2 |   3 |
| 0 | 1 |  4 |   9 |
| 0 | 1 |  8 |  27 |
| 0 | 1 | 16 |  81 |
| 0 | 1 | 32 | 243 |
