Merge tables

Merge tables

[Hector Villafuerte]

Hi,
I've just discovered Org and are truly impressed with it; using it for
more and more tasks.

Here's what I want to do: I have 2 tables with the same number of rows
(one row per subject). I would like to make just one big table by
copying the second table to the right of the first one. This is a
no-brainer in a spreadsheet but my attempts in Org have failed. Any
ideas?

By the way, thanks for this great piece of software!

Rectangular cut and paste maybe?

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).

If you only want to put the second table at the right of the first one I think
that the functions kill-rectangle and yank-rectangle are enough. Select the
second table (without the first | char) and run the command kill-rectangle (C-x r
k), then put the cursor at the end of the first line of the first table and run
the command yank-rectangle (C-x r y).
