Hello,
Some follow up on this problem I thought that I messed up the org-mode update because I had some org files open during the updates. I reinstall emacs and org-mode to the latest but I still get the problem. Performing M-x org-html-export-to-html on the file below ends up in an error because tabular* is wrongly added instead of tabular. I could reproduce the problem with the version org-mode that comes with the latest emacs version as well. -- test.org #+OPTIONS: H:3 num:t toc:nil \n:nil @:t ::t |:t ^:t -:t f:t *:t tex:imagemagick title:nil author:nil date:nil #+LATEX_HEADER: \usepackage{booktabs} \begin{tabular}{lll} \toprule 4 & 2 & 3 \\ 5 & 6 & 8 \\ \hline \end{tabular} \end{table} Best regards, Jeremie GNU Emacs 28.0.50 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.5, cairo version 1.16.0) of 2020-09-01 Org mode version 9.3.7 (release_9.3.7-725-g7bc18e @ /home/djj/src/org-mode/lisp/)
