Can you add table borders to TRx?

Wayne & Laura,  c: Public Low Vision

I've been chatting with Alastair about the color contrast of native html
table borders.  We were trying to figure out how we can make sure that
people with low vision can see table borders if the author has made those
table borders with a low color contrast.

Since those table borders are rendered by the browser, and could be
controlled by css (or perhaps even included in TRx)....I was wondering if
we could eventually cover table border contrast in the proposed SC for
Adapting Text.  We don't have to pick it up this round....but...Alastair
and I think that table borders are not a strong fit for either of the
following proposed WCAG 2.1 SC

   - Graphics Contrast - this proposed SC is focused on author created
   images.  Table borders are not author created images.
   - User Interface Control Contrast (Minimum) - this proposed SC is
   focused on interactive user interface controls (and table borders are not
   interactive controls).

Thinking through what other types of non-text content that is rendered by a
browser...I can only think of table cell borders, horizontal rules, and
possibly unordered list bullets (but those could be considered characters
too).

Or...would we really need to have a new proposed SC..something like
"Adapting Visual Formatting".  Ooooooo....what about Adapting Text and
Visual Formatting?

Thoughts?

P.S.  Yes...I realize this is a very painful question...since just getting
Adapting Text through is proving to be quite challenging.  But I wanted to
make sure all of us took a moment to think about color contrast of table
borders and where this fits in to our long range plan.
