Actually, this is what I thought of when I wrote ‘using another 
language than TeX’. And you are certainly right; that would be an 
easier solution.

The command \tabularnewline has the same effect as & or \cr inside the 
loop: It stops prematurely.

A possibility is to create the table using \vbox’es rather than a 
specific LaTeX environment. This seems to solve my problem, as the 
table itself is quite simple, but rather long (about 40 pages, so I 
would have had to use supertabular or something of the like). However, 
I have (re)discovered a ‘feature’ which I do not quite understand. In 
the following piece of code, the \vbox’es (or rather \vtop’s, but that 
changes nothing) line up horizontally:

\vtop{\hsize = 4cm 1st LINE\\ 2nd LINE}%
\vtop{\hsize = 4cm TEXT}%
\vtop{\hsize = 4cm TEXT}

Here, the \hfil will have zero width. However, if I remove the \hfil 
(and put nothing before the first \vbox), the \vbox’es will stack 
vertically. Could anyone explain the logic behind this behaviour? (A 
\hfil is not always a good idea, either.)

Thank you for your help.
