I'm not sure whether this is an issue with orgmode or my recent Emacs build, I'm struggling to export orgmode tables from a python code block to html/pdf. Version info: orgmode 9.5.4 GNU Emacs 29.0.50 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.20, cairo version 1.16.0) of 2022-07-29 Note my Emacs is a custom build with native compilation, json and GTK support - which may be an issue - i.e. taken straight from the latest code in github. My simple test case would be something like: #+begin_src python :results value raw :exports both import pandas as pd from tabulate import tabulate df = pd.DataFrame({'A': [1, 2], 'B': [3, 4]}) return tabulate(df, headers=df.columns, tablefmt='orgtbl') #+end_src If I execute the code in the editor the org-mode table appears in the results. If I export to html or pdf I get the error: org-babel-insert-result: Wrong type argument: markerp, nil. Even a simple example such as the following fails to export but will show inline. #+begin_src python :results table :exports both return [['A', 1], ['B', 2]] #+end_src Stack trace on failure is below - hence why I was concerned with the custom Emacs build: jit-lock--run-functions(248 324) jit-lock-fontify-now(248 #>) org-font-lock-ensure(248 #>) org-table-align() org-table-next-field() funcall-interactively(org-table-next-field) #(org-table-next-field nil nil) call-interactively@ido-cr+-record-current-command(# org-table-next-field nil nil) apply(call-interactively@ido-cr+-record-current-command # (org-table-next-field nil nil)) call-interactively(org-table-next-field nil nil) org-cycle() org-babel-insert-result("| | A | B |\n|----+-----+-----|\n| 0 | 1 |..."
