On GNU/Linux with Orca 3.12, the tables are not processed properly. Normally, Orca can be set to speak the cells coordinates and only read the current cell (except if it's requested to speak the whole ;ine).
On LO now, even if Orca is set properly, the screen reader reads lines and not cells, and it doesn't give the cells coordinates. Browsing a table is so much less convinient. The Orca bindings, al-shift-arrow keys, to browse a table, don't work.
To reproduce, create a new table and listen to Orca, testing the various settings and the bindings to move inside a table.
Confirmed on IRC on version 4.2.42
I add a debug message from Orca. The 1st part is for another bug I'll report quickly with Open and Save as boxes. The second part of the debug file matches to orca in tables.
This bug has just been fixed in Orca.
