Hi Hector,

Here are two ways of doing this in org-babel.

* Binding tables together by columns

Suppose the tables are

#+tblname: tab1
| 1 | 2 | 3 |
| 7 | 8 | 9 |

#+tblname: tab2
|  4 |  5 |  6 |
| 10 | 11 | 12 |

Here's a solution in emacs lisp:

#+srcname: column-bind-elisp(a=tab1, b=tab2)
#+begin_src emacs-lisp 
(mapcar* 'append a b)
#+end_src

#+resname: column-bind-elisp
| 1 | 2 | 3 |  4 |  5 |  6 |
| 7 | 8 | 9 | 10 | 11 | 12 |

And here's a solution in R, which has the advantage that it copes with
column names (and the code is even simpler).

#+tblname: tab3
| a | b | c |
|---+---+---|
| 1 | 2 | 3 |
| 7 | 8 | 9 |

#+tblname: tab4
|  d |  e |  f |
|----+----+----|
|  4 |  5 |  6 |
| 10 | 11 | 12 |

#+srcname: column-bind-R(a=tab3, b=tab4)
#+begin_src R :colnames t
cbind(a, b)
#+end_src

#+resname: column-bind-R
| "a" | "b" | "c" | "d" | "e" | "f" |
|-----+-----+-----+-----+-----+-----|
|   1 |   2 |   3 |   4 |   5 |   6 |
|   7 |   8 |   9 |  10 |  11 |  12 |


Once someone has written them, even simple code blocks like these can be
stored in the "library of babel" for users who aren't familiar with a
suitable programming language (I'll add them on worg).
