`render_table` macro broken with new version of sqlalchemy

[Demetriex]

The example should work properly without the title.

if you run the example in debug mode the error says 'AttributeError: _data'.

the get_table_titles function is broken with sqlalchemy>=1.4.0

I have the same problem.

I will take a look into it next week then make a new release. PR is welcome.

For a temporary fix, you can downgrade the version of SQLAlchemy:

pip install -U sqlalchemy==1.3.24

Just released 1.5.2 to fix this, give it a try!
