Tables are for tabular data. Go read W3C accessibility guidelines.
Tables are not for visual layout all over the screen.
CSS does that nicely without messing with accessibility.

I was referring to the use of tables.
Plain divs, correctly sequenced, are comprehensible via any reader,
CSS or not. Just down to the author to write the content in
an appropriate order so that CSS enhances visual and does nothing
negative to audio presentation.
