RE: WG discussion: Nov 5, 2013: role=group technique

Hi Bruce,
Role=presentation on the table will  prevent the table being exposed as a table to AT. The contents of the table are still available to all. A screen reader user will not be tempted to navigate this content as a table if the role were not there.  
Rightho,
Sailesh

 Thanks Sailesh.  I thought aria
 role=presentation causes AT to ignore the element.  So
 would this not hide the table and the content therein?

 Bruce,
 With respect to your comment on use of role=presentation on
 the table with credit cards in example#2:
 It is a layout table and role=presentation helps to remove
 any ambiguity in its interpretation by AT.
 NVDA, for instance will expose it as a table in FF if the
 role is absent.
 
 Regards,
 Sailesh
