DataTable's accessibility use of the id and headers attributes to table cells so screen readers can identify the cells that relate to the headers for blind people

[Paul Bors <pa...@bors.ws>]

Hey guys,

 

I've noticed during a scan of our webapp in http://achecker.ca that the
Wicket DataTables do not quite support accessibility when it comes to
mapping its table cells to the table headers via the TD element's ID and
HEADERS attributes. Is that true or am I using the wrong component?

 

I'm just asking before I start overriding methods from the DataTable to
implement this.

And if I do this, shouldn't I submit a patch back to you guys?

 

To see what I'm talking about, simply take any of the HTML source code of a
Wicket DataTable with more than one row in it and with a HeadersToolbar and
then scan it via http://achecker.ca and notice the errors and suggestions
given:

~ Thanks in advance,

Hi,

Most of the default components do not support well ARIA or similar
accessibility specifications.
Patches are welcome, as always!
