Yes, I meant the attribute. Thanks for catching that.
Sometimes we are forced to use content coming from the clients, and in
those instances we donÂ¹t always have the ability to persuade them to break
up tables (or charts and other infographics) into pieces easier to
comprehend. But youÂ¹re right that this generally having to describe table
structure is a sign that the table is poorly designed!
HereÂ¹s another problematic scenario: when we have to make a PDF with an
image of a data table accessible. Dumping tons of data into the ALT text
for the image is horrific. I can only imagine the curses that screen
reader users must utter. How can anyone process data that way?
