Is able to parse tables of the form: +=====+=====================+ | Foo | Bar | +=====+=====================+ | x | This is a long line | | | that is spread out | | | over multiple lines | +-----+---------------------+ Into: [['Foo', 'Bar'], ['x', 'This is a long line\nthat is spread out\nover multiple lines']] The draw_table function needs to be written still, though.
