[Feature Request] Add markdown table rendering style options

Bug Description

I prefer old style markdown table rendering UI. this new table style makes original output and rendered text different, and horizontal divider between rows makes the table poorly readable & comsuming viewport heights, which makes me to scroll more, hard to glance the output.

Or, could you make an option to choose how the markdown table to be rendered? (ex. raw, table table with no row-wise horizontal diveder) . like table styles in python rich tables (https://rich.readthedocs.io/en/latest/tables.html)
