According to Success Criterion 1.3.1 (Info and Relationships), the relationship between table headings and table data (ie. th and td elements) must be programmatically determinable. This can be done using either the "scope" attribute on th elements, or "headers" attributes on td elements - depending on the number and type of headings.
Because this table contains two levels of headings, the "headers" attribute method must be used. In this case, the table data cell named "Cell 1Aii" does not contain one of these attributes.
