Display the code for this table (abbreviated to 3 rows)
See a Bobby report on this page
This is an example of how one would go about coding a table to be more usable by non-visual users. According to the W3C's HTML 4.01 specification:
"Non-visual user agents such as speech synthesizers and Braille-based devices may use ... TD and TH element attributes to render table cells more intuitively."
The following example includes the ID and SCOPE attributes of the TH element (both would not usually be used together; they were combined for the purposes of this example), and the HEADER attribute of the TD element.
A speech synthesizer might render this table as follows:
