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
