Differences
Well tagged PDF:
The 'TD' element denotes a standard table data cell in Well-Tagged PDF, holding the primary content of a table.
Data cells should be correctly nested within a 'TR' element and aligned with their respective header cells to maintain a coherent structure.
PDFUA:
In PDF/UA, the 'TD' element represents a data cell that must be accessible. It is essential for conveying the table’s content in a way that assistive technologies can interpret.
TD elements must be tagged with proper associations to header cells and include alternative text where necessary to support accessible navigation.
