Re: Using ARIA grids

You might have missed the purpose of my question. I wasn't trying to
explain the purpose of ARIA. It sounded like you said developers thought
they had to use an ARIA grid instead of a native <table> because of
scrolling issues. My question was that since ARIA doesn't affect behavior,
there should not be any limitation of behavior between an ARIA grid and a
native <table>. I was trying to get clarification if that's what the
developers thought.

Now, there might be a difference in behavior in how a screen reader
surfaces a grid vs a table with regards to screen reader shortcut keys used
in navigating a table. I've seen varying levels of support for role="grid"
between browser and screen reader combinations.
