[O] Programatic Org Table Groups

[Ken Mankoff]

I'm generating Org tables via code and the =:results table= option. By the way 
the "tabulate" python package works great to convert Pandas DataFrames to Org 
Tables.

I can generate tables this way, but if I try to add groups, I cannot. The first 
column with the special "/" character seems to be stripped. Below I can print 
two "//", but if I try to print one, the row is removed.

Is this a bug? Does anyone have a workaround for this?

Thanks,

  -k.
  

#+BEGIN_SRC python :results table
  import numpy as np
  val = np.arange(9)
  tab = np.append(np.array(['//','<','>']), val)
  return tab.reshape(4,3)
#+END_SRC
#+RESULTS:
| // | < | > |
|  0 | 1 | 2 |
|  3 | 4 | 5 |
|  6 | 7 | 8 |
