Accessibility for Tables

The tables generated by crouton aren't rendering properly in a screen reader, via messages from 2 additional needs addicts in the Carolina Region. If the headers could be marked up so a screen reader properly reads the headers and content it would make it more accessible to addicts who depend on assistive technology on websites. WebAIM provides guidance to markup the headers and rows - https://webaim.org/techniques/tables/data . Additonally WCAG offers guidance on the markup in the quick reference - https://www.w3.org/WAI/WCAG21/quickref/. The suggested target would be Level AA.
