508-G, 508-H Administration / Page management page headings do not provide TH element or the SCOPE attribute required to structurally define a table or to programmatically-link the column headers with each column cell.

To meet accessibility guidelines, data tables such as the below require
that row and column headers must be defined using the TH element that
allow assistive technology (specifically screen readers) to access these
headers and connect these values to their respective data cells using the
SCOPE attribute. For sighted users, determining this relationship between
columns, rows and cells is an intuitive task. For screen reader users, this
same comprehension of structure and relationships comes from properly
coded data tables using tags like the TH element and its SCOPE attribute.

This violates 508 certification requirements:
§ 1194.22 (g) Row and column headers shall be identified for data tables and
§ 1194.22 (h) Markup shall be used to associate data cells and header cells for data tables that have two or more logical levels of row or column headers.
