"...since the purpose of the check box is readily apparent to sighted
users."
I looked at the screen capture you sent us, and it wasn't readily apparent
to me (I am sighted) that the checkbox was for deleting the item.
However, I am not a regular user of this site/page, so that does make a
difference. Regardless, however, it seems to me that this is more of a
usability issue. Users reading the page with a screen reader should have
no trouble identifying the contents of the "checkbox column", since all
the cells in that column are checkoxes and there is only one column with
checkboxes. Of course there should be a way to identify what row the cell
is in, but this does not concern the column heading.
In any case, the checkboxes are not likely to be any more ambiguous for
non-sighted users than for sighted users. From the accessibility
standpoint it's probably fine. And since this is a forum on
accessibility, not usability, I won't go there.
