Just curious, but will NVDA recognize row and column titles if they are defined in the Excel spreadsheet itself, rather than after the fact by telling the screen reader which row is the column titles and which column is the row titles?
I know that JAWS will pick up on row and column titles defined within the spreadsheet without needing to define it to the screen reader. Of course that means either the creator of the spreadsheet, or you the screen reader user, need to have defined these in Excel itself.
