Firstly, you should make @summary display on :hover, and place it 
  *above* the table, so that it doesn't disturb the layout. Then 
it should not disturb you any more than @title content generally do.

/* Probaly only works in Opera - other UAs require "more".
    For "more", see: http://malform.no/html5/summary+css */
	content:"Summary: " attr(summary);

But ideally, the @summary attribute should be activated *not* by 
hovering over the table, but by hovering over the caption. Thus we 
create a link between caption and @summary and encourage authors 
to add both a caption and a summary.
