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 */
table:hover:before{
display:table-caption;
content:"Summary: " attr(summary);
background:yellow;
position:absolute;}
table:active:before{
display:none;}
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.
