Let suppose our program output many formatted tables.

For instance :

#+Name: Scores #+BEGIN_SRC python :results output raw from random import randint li ='''Max Charlie Cooper Buddy Jack Rocky Oliver Bear Duke Tucker'''.split() print( "|{0:8s}| {1:3s} | {2:3s} | {3:3s} |".format( "Name","str","agi","int" )) for f in li: print("|{0:8s}| {1:3d} | {2:3d} | {3:3d} |".format( *( [f]+[randint(0,20) for x in range(3)]) )) #+END_SRC #+Call: Scores()

The evaluation of the code block will produce an output similar to this

#+RESULTS: | Name | str | agi | int | | Max | 17 | 15 | 16 | | Charlie | 2 | 5 | 19 | | Cooper | 3 | 5 | 5 | | Buddy | 9 | 6 | 9 | | Jack | 11 | 14 | 19 | | Rocky | 19 | 1 | 2 | | Oliver | 5 | 17 | 5 | | Bear | 0 | 17 | 17 | | Duke | 16 | 8 | 19 | | Tucker | 14 | 13 | 9 |

When exporting, the #+CALL is evaluated, and its results gets exported.

Question: how to automate the insertion of something like 

#+ATTR_LaTeX: :center nil :align |p{5cm}|l|l|l|

on top of the table in the results section ?

Any proposal is welcome, be it by outputting by value, hooking the export, creating a latex header... or indicating any appropriate org function.

A :prologue header is appended to the body of the block before execution:

#+Name: Scores #+header: :prologue print('#+ATTR_LaTeX: :center nil :align |p{5cm}|l|l|l|') #+BEGIN_SRC python :results output raw :exports results :eval yes from random import randint li ='''Max Charlie Cooper Buddy Jack Rocky Oliver Bear Duke Tucker'''.split() print( "|{0:8s}| {1:3s} | {2:3s} | {3:3s} |".format( "Name","str","agi","int" )) for f in li: print("|{0:8s}| {1:3d} | {2:3d} | {3:3d} |".format( *( [f]+[randint(0,20) for x in range(3)]) )) #+END_SRC #+results: Scores #+ATTR_LaTeX: :center nil :align |p{5cm}|l|l|l| |Name | str | agi | int | |Max | 9 | 13 | 17 | |Charlie | 12 | 7 | 10 | |Cooper | 16 | 19 | 7 | |Buddy | 16 | 2 | 13 | |Jack | 17 | 10 | 20 | |Rocky | 0 | 19 | 13 | |Oliver | 17 | 2 | 6 | |Bear | 19 | 20 | 17 | |Duke | 8 | 19 | 9 | |Tucker | 1 | 10 | 7 |

You can do this with the :post header and a named block that adds that. https://orgmode.org/manual/post.html#post

Here is an example modified from that page.

#+name: attr_wrap #+begin_src sh :var data="" :results output echo "#+ATTR_LATEX: :center nil :align |p{5cm}|l|l|l|" echo "$data" #+end_src #+Name: Scores #+BEGIN_SRC python :results output raw :post attr_wrap(data=*this*) from random import randint li ='''Max Charlie Cooper Buddy Jack Rocky Oliver Bear Duke Tucker'''.split() print( "|{0:8s}| {1:3s} | {2:3s} | {3:3s} |".format( "Name","str","agi","int" )) for f in li: print("|{0:8s}| {1:3d} | {2:3d} | {3:3d} |".format( *( [f]+[randint(0,20) for x in range(3)]) )) #+END_SRC #+RESULTS: Scores #+ATTR_LATEX: :center nil :align |p{5cm}|l|l|l| | Name | str | agi | int | | Max | 12 | 4 | 10 | | Charlie | 15 | 10 | 10 | | Cooper | 17 | 13 | 20 | | Buddy | 6 | 15 | 11 | | Jack | 8 | 15 | 16 | | Rocky | 1 | 16 | 6 | | Oliver | 9 | 11 | 14 | | Bear | 10 | 6 | 3 | | Duke | 2 | 19 | 1 | | Tucker | 8 | 0 | 2 |
