Link to HTML 5 definitions of column header and row header?

[WilcoFiers]

There are a few uses of the term "column header" and "row header" such as the following:

th (is neither column header nor row header, and ancestor table element has table role)
[wai-aria-1.1] | cell role

source: https://w3c.github.io/html-aam/#el-th

I'm assuming that "column header" and "row header" here mean column header / row header as defined in HTML:

• https://html.spec.whatwg.org/multipage/tables.html#row-header
• https://html.spec.whatwg.org/multipage/tables.html#column-header

This is not immediately obvious. It would be helpful if this was clarified in some way, for example to link to these HTML definitions. This seems related to #53 as well, which got closed.
