Re: Does 5.1 absolutely require TH?

When taken by itself, 5.1 may not *absolutely* require use of <th> to

column headers and one column of row headers).

John, I am curious to   understand why you feel this way and why you are  roping 5.1 with Guideline 3.  I think 5.1 is quite clear and distinct. Checkpoint 3.3 (P2) says use stylesheets for layout  and  that suggests use of CSS instead of layout tables. None of the other checkpoints in G3 refer to tables.
And do you agree to the  accessibility problem I pointed out while trying to navigate simple data tables without column headers?
