[Blindmath] Another test of matrix accessibility

[Steve Jacobson]

Michael,

Window-Eyes with Internet Explorer 8 reports the first table as having Four rows and three columns.  With table 
navigation keys, I can move across the rows and up and down columns.  Since this is an HTML structure, I wonder 
why VoiceOver sees this differently.  This is the kind of thing that gets so frustrating when trying to come up with ways 
of making things accessible.  In this case, it isn't a big deal since the first example is not the preferred one, but one 
would think screen readers would all see tables the same way, although I suppose it could be the web browser.  
Interesting.

Best regards,

Steve Jacobson
