WIP | Fix handling for table_style to prevent repeated re-splitting

[kdipippo]

TODO for me:

• Migrate tests to use existing test.py file, remove pytest dependencies.
• Sanitize HTML input and commit to this directory
• Update README for setting table style
• Test for invalid table style, returns the following long error:

Hello @kdipippo! Thanks for contribute with this project! Could you explain why create a separated unitttest file instead add this test to tests/test.py? There you don't need to setup and clean because there is already methods to do this for you.

Oh sweet! Thanks for the comment! I'll rework to use test.py. My bad, I missed that this repo has unit testing set up.

Going to close this and re-open as an issue first and then re-make the PR correctly
