Originally filed as NVDA issue: https://github.com/nvaccess/nvda/issues/12767

STR (with the NVDA screen reader):

  1. Visit https://cdpn.io/aardrian/debug/xxqYyaa
  2. Press 2 to navigate to the heading "3. SVG with Table Roles".
  3. Press T to navigate to the table that immediately follows that heading.
  4. Navigate into the table and then move among cells using Ctrl + Alt + arrow key.
    • Actual behavior: NVDA reports "Not in a table cell".
    • Expected behavior: I can navigate the SVG as any other well-formed HTML table.

I investigated this briefly. The IAccessibleTable and IAccessibleTable2 interfaces are exposed on the table, but calling nRows, nColumns, etc. returns CO_E_OBJNOTCONNECTED. On the cells, the IAccessibleTableCell interface isn't exposed at all.

I'm not sure whether this is Windows specific or not; I haven't dug into that.
