Converting nested tables [to latex ; from docx or odt]

Converting nested tables [to latex ; from docx or odt]

Dear all,

I am new to pandoc, and searched this forum of discussion without finding 
any similar issue. Here is a bug I think I found. I reduced the input 
document to an almost minimal form, and it is attached to this message.

I am working under ubuntu 20.04, and downloaded the latest pandoc 2.14.1.

The issue is related to a document that contains an array, and inside one 
of the cells of this array, there is another array.


1. Bug from .docx to latex

Here is the conversion line I used :

pandoc --standalone --extract-media=. -t latex -f docx Nested_arrays.docx 
-o Nested_arrays.tex

When doing this conversion, pandoc sees that there is a table inside the 
table. Hence, pandoc produces a longtable nested inside another longtable. 
And this produces a latex error

! Forbidden control sequence found while scanning use of \LT@nofcols.

I'm not using longtables usually in my latex code, but after some search on 
the internet, maybe the problem comes from an impossibility to nest a 
longtable inside another longtable, hence the output should be changed ? 
Here is how I fixed this error, by modifying the .tex output by pandoc:

* changing the longtable inside the bigger one to a tabular
* and, of course, removing \endhead of this inner array because tabulars do 
not have \endhead


2. Bug from .odt (to latex, to markdown...)

I thought that maybe the bug was linked to the .docx document I received 
from my colleague, so I saved the document to a .odt document. And this is 
way worse ! This time, the line containing the nested array is simply not 
output at all, neither if I ask to produce latex, nor if I ask pandoc to 
produce markdown.

pandoc --standalone --extract-media=. -t latex -f odt Nested_arrays.odt -o 
Nested_arrays.tex


3. Finally, but this time I saw that this has already been discussed : as 
you can see, the inner table would be clearer for pupils with all lines 
drawn, because it is intended to be a clear array that pupils have to fill. 
If there was a way to specify that "I want to keep all those ugly lines 
inside the output latex code please, whatever you think of this design 
choice", this would be awesome :)


Thanks in advance for your replies, and have a nice day.

Yann

In general I don't think we have very good support for nested
tables.  I'm sorry, I don't have any particular suggestions that
can help.  But feel free to file a bug report or two if you like.
