Re: Treegrid Question

If you have <table role="treegrid">, then NVDA doesn't think table is a
table anymore. I can't navigate to it with the T key or use table
navigation nor hear table headers.

With JAWS, all the standard table navigation works and headers are read.

With VoiceOver, I can use the rotor to navigate to the table so it still
thinks it's a table, and I can use the rotor to navigate by rows, but when
I navigate across a row, column headers are not read. So it sort of thinks
it has a table but doesn't seem to have all the native table features.

So support for role="treegrid" seems a bit spotty.
