When I export to latex the following simple file:
#+Title: Example
#+OPTIONS: H:2 ^:{} f:t toc:nil author:nil
#+LATEX_HEADER: \usepackage[backend=bibtex]{biblatex}
#+LATEX_HEADER: \addbibresource{$HOME/Bibliographies/bibliography}
#+LATEX_HEADER: \graphicspath{{$HOME/Pictures/images/}}
# #+BIBLIOGRAPHY: ~/Bibliographies/bibliography
# #+BIBLIOGRAPHY_STYLE: plain
* Foo
#+CAPTION: Capitals
#+NAME: tab:capitals
| Country | Capital |
| | |
|-----------+----------|
| Australia | Canberra |
| Japan | Tokyo |
| France | Paris |
* Bar
Please look this flamboyant table: Table [[tab:capitals]].
I get a result where the reference [[tab:capitals]] is renderd with "??" in latex, instead of "1".
I noticed that it works ok if I remove the #+LATEX_HEADER: \addbibresource{$HOME/Bibliographies/bibliography} line, but I need it for my bibliography and citations.
The variable org-latex-pdf-process is set to (list "latexmk -pdf -shell-escape %f") in my configuration. This is the .tex produced

The reference and label match in the tex file, but still fail to produce a correct pdf output. What is the link between \addbibresource and reference to table producing this?
Thanks for help :)
My setting of org-latex-pdf-process was the culprit:
(setq org-latex-pdf-process (list "latexmk -pdf -shell-escape %f"))
It was set like this because I had bibtex citations not working, and had this workaround from somewhere... But this broke reference to tables.
So to fix this, I went back to the original value in emacs documentation:
(setq org-latex-pdf-process
'("%latex -interaction nonstopmode -output-directory %o %f"
"%latex -interaction nonstopmode -output-directory %o %f"
"%latex -interaction nonstopmode -output-directory %o %f"))
However this does not run bibtex. So to get citations to work, I need to add "bibtex %b" between calls to latex compiler:
(setq org-latex-pdf-process
'("%latex -interaction nonstopmode -output-directory %o %f"
"bibtex %b"
"%latex -interaction nonstopmode -output-directory %o %f"
"%latex -interaction nonstopmode -output-directory %o %f"))
Thanks to @Dieter.Wilhelm 's solution from this thread!
