| Aloha Rainer,
Perhaps this will work? Eric Schulte wrote a function to make a LaTeX table out of an Org-mode table. You should be able to call it from within a LaTeX source block that tangles to a suitably named file. There is an added benefit in the support for booktabs rules, so you'll need to have the booktabs package installed.
hth, Tom

*** booktabs
This block can be used to wrap a table in the latex =booktabs=
environment, it takes the following arguments -- all but the first two
are optional.
| arg | description |
|-------+--------------------------------------------|
| table | a reference to the table |
| align | optional alignment string |
| env | optional environment, default to "tabular" |
| width | optional width specification string |
#+srcname: booktabs
#+begin_src emacs-lisp :var table='((:head) hline (:body)) :var align='() :var env="tabular" :var width='() :noweb yes :results latex
(flet ((to-tab (tab)
(orgtbl-to-generic
(mapcar (lambda (lis)
(if (listp lis)
(mapcar (lambda (el)
(if (stringp el)
el
(format "%S" el))) lis)
lis)) tab)
(list :lend " \\\\" :sep " & " :hline "\\hline"))))
(org-fill-template
"
\\begin{%env}%width%align
\\toprule
%table
\\bottomrule
\\end{%env}\n"
(list
(cons "env" (or env "table"))
(cons "width" (if width (format "{%s}" width) ""))
(cons "align" (if align (format "{%s}" align) ""))
(cons "table"
;; only use \midrule if it looks like there are column headers
(if (equal 'hline (second table))
(concat (to-tab (list (first table)))
"\n\\midrule\n"
(to-tab (cddr table)))
(to-tab table))))))
#+end_src
--8<---------------cut here---------------end--------------->8---
once loaded it can be applied as here

Based on a discussion in the thread "Problem with PROPERTIES :OPTIONS: when exporting subtree", The idea came ub by Mathew Lundin to be able to "send the results or a source code block (either executed code or exported org snippets) via babel to a target in an external file.".
The scenario or context in which the idea came up:
I am using org babel for literate programming and I document my parameters for simulations in a table in org. Now when writing a paper, for which I use a different program (I use LyX), but I still would like to include the tables from my original org file in them. Therefore I was looking for a possibility to export ONLY the table into a .tex file, so that it can be included in the LyX / LaTeX via \input{theTable.tex} . Therefore I would need an export of the table in LaTeX format, but no preamble or anything. As far as I was told, this possibility does not exist in org.
So Mathew's / my question is if it would be possible to include a functionality to "send the results or a source code block (either executed code or exported org snippets) via babel to a target in an external file.".
Cheers,
Rainer
