Re: Grid support for aria-setsize and aria-posinset

I see.  I'll report the issue to Freedom and NVDA then in the hopes that they can pick up the support you are providing in Firefox in future releases.

Regarding my example not making use of position and setsize on column headers: wasn't sure how to handle that.  Column headers aren't part of the actual paged data set, so I didn't think that they should have position and setsize defined.  Do you know what I mean?  Any guidance on how to improve the example would be appreciated.

I'm testing using FF 3.6.12 using both NVDA 2010.2 and JAWS 12 and don't hear the row positions announced according to the positions I have defined.  Could that be due to the screen readers not yet supporting the group position that you are exposing?  Here is a like to my test example if you would like to take a look to see if there is anything I am doing wrong.

The use case would be using a datagrid to present paged data and only the current page is present in the DOM.  In such cases you would want to communicate the ordinal position of a row relative to the current page and total number of pages and rows.
