B.101. speak-header

For use by aural (speaking) browsers for the visually impaired, this property controls how table headers are read. As the browser reads out the contents of each cell in the table, it can either read all the headers for each cell before the cell's contents, or read only those headers that are different from the headers of the previously-read cell.

Inherited: Yes
