Does anyone have any experience with treegrids? Treegrids may solve a
problem I have with displaying a subset of tabular data, with the full row
info displayed when expanded. I am fooling around with the WAI-ARIA
Authoring Practices pattern and example for treegrid, but attempting to
navigate the example as a table, I am not hearing the column headings read
out. Since the data is tabular that seems like a drawback.
For your convenience, here is the pattern

and the example

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.

Steve said "NVDA doesn't think table is a

Sorry, I didn't mention that I was using NVDA and Chrome. Hmmm...I don't
think NVDA has the largest market share, but I'm less likely to use
something that won't work in NVDA.

I was going to suggest filing a bug with NVDA but it looks like that was
done 6 months ago.
https://github.com/nvaccess/nvda/issues/9715
I just added a few comments to that bug. While you can't find the treegrid
using the T shortcut key, once you're in the treegrid, if you switch out of
browse mode to focus mode (escape key), you can then navigate within the
table using standard table navigation keys.
Minimally, NVDA should let you find the treegrid with T.
