SuperTables: Accessibility audit shows missing ‘Main roles’ which helps users to skip sections.

Aria Rule: Bypass repeated blocks by setting role to “Main” 

Since web sites often display secondary, repeated content on multiple pages (such as navigation links, heading graphics, and advertising frames), keyboard-only users benefit from faster, more direct access to the primary content on a page. This reduces keystrokes and minimizes associated physical pain. Since SuperTables is just one page and there are navigation shortcuts to move around. This does not affect the accessibility of SuperTables. Check the Product Guide for more information.
