Thanks for sending that example.  F91: Failure of Success Criterion 1.3.1
for not correctly marking up table headers should then be updated to let
folks know that some data tables do not require headers.  Honestly though I
think it would be very confusing for a screen reader user without any
headers.  Perhaps there should be a way to tell the screen reader that no
headers are present otherwise it might guess at headers?  Screen readers
would likely read the row and column numbers – all of the numbers would
most likely be confused with the numbers in the cells.  I would think that
a more accessible Sudoku would work in a forms/focus mode with some sort of
ARIA markup that might indicate the columns and rows through letters are
something other than numbers.

What I was attempting to say is that according to my understanding of WCAG
2 – some use of TH, td with scope, or ids and headers are required for any
table not used for layout purposes.



some techniques may recommend this, but is/should not be a requirement,
there are cases where such markup is not required.

there is an example in the HTML spec: refer to example under "Here is an
example of a table being used to mark up a Sudoku puzzle. Observe the lack
of headers, which are not necessary in such a table."
