Could it be due to using it with myst_parser extension and the links / documents being in markdown format?

@noname77 Thank you for using this extension.
Sure, I want to resolve this issue, but it's tough to reproduce with the information you wrote.

Could you please provide the following details?

  1. dependencies in your environment
    • output of pip list is helpful.
  2. extensions in conf.py
  3. reST or Markdown file
    • I want to check the markup of the table as exceptions are being thrown in the depart_table method.
  4. If you have the code publicly available, could you share the repository URL for further examination?

Thank you for the detail information.

Sounds great!

I tried using the same versions of the libraries, but IndexError is not reproduced.
Please let me know if you notice anything about the following procedure.

It seems like there's no link in the example table.
Could it be an issue with sphinx-new-tab-link?
