I found the culprit.
I have set my background color to black and forground color to white.
Yet when I adust the org-format-latex-options to see the preview white on
black, the tabular environment displays the expected color setting but not the
table environment.
So far I can only change the background color to preview the table environment
but not the foreground color. I'll try to find a solution and come back if I
do. In the meantime any idea to fix this issue is welcome :-).
Below are the settings with which I hope you could reproduce this phenomenon.
(set-background-color "black")
(set-foreground-color "white")
(setq org-format-latex-options '(:foreground "white" :background "black" :scale
1.4 :html-foreground "Black" :html-background "Transparent" :html-scale 1.0
:matchers ("begin{.*[^table]}" "end{.*[^le]}" "$1" "$" "$$" "\\(" "\\[")))
Thanks again,
Jeremie
