Table headers not required when role="presentation"

[robfentress]

UDOIT flags a table as being in error if it does not contain table headers (<th>). This rule should check whether or not role="presentation" has been used with the table and should only report it as an error if this role has not been set. With ARIA, it is now okay to use tables for layout, if the role is set to "presentation" (as long as the table makes sense when linearized), since this strips out any semantics.

This standard is in a rough draft state: w3c/aria-practices#182

When it is a published standard, we will merge Emily's code.

I guess I never got back to this. That particular issue I mentioned in 2018 is still open, but it looks role="presentation" for tables made it into the standard: https://www.w3.org/TR/wai-aria-1.0/roles#presentation

I'll be reviewing Emily's code and seeing if it can still be merged after all these years.
