Need standard way to distinguish data tables from layout tables

State:

CLOSED

Product:

ARIA 1.1 Core Mapping Specification

Description:

This belongs in the HTML Accessibility API Mapping doc. I'm not sure which product to use for that, so putting it here where we won't lose it.

Let's create a standard algorithm for browsers to decide whether to expose a <table> as a table structure in the accessibility API.

IE implements the UIA table pattern if cell (0,0) is a <th>
