Subject: JAWS 9 and the Layout Table Algorithm
No previous message | Next message →

Does anyone know how JAWS 9 determines if a table is a layout or data
table?

I seem to be looking at a HTML table with 2 columns and 3 rows that JAWS
thinks is a layout table, although the author intends it to be a data
table. It looks like all the cells have content of some type.

Thanks!
Tim

Hi Tim,

I don't know for sure, but I imagine having thead, tbody and th elements
would make it an obvious data table, since layout tables are probably
going to be all td's.

Is JAWS not announcing the table at all, or is it just not announcing
row and column headers? On my system, which is configured for JAWS not
to announce layout tables, JAWS will announce any table that includes TH
elements. I can also navigate to those tables using the "t" key.

Wow! I shudder to think of how many data tables on our site have no TH elements. One of many things to put on the list for our developers to clean up!

Chris,

Thanks for the suggestion. I just tried adding th elements. It
evidently already had a tbody element, but no thead. Unfortunately, its
still treating it like a layout table.

Thanks!
Tim

Mike,

Thanks for the suggestion. JAWS isn't announcing the table--like it
thinks it is a layout table. I tried adding in th elements and it seems
to ignore them.

I guess I might need to rebuild the table from scratch and keep adding
back items to it until I can recreate the problem.

Thanks!
Tim

Tim,

Are you using the caption element and the summary attribute? If not,
these may help identify the table as data not layout.

Vicki. :-)

Tim,

If you would like to send me a link, I will take a look and see if I can
figure out what's going on for you.
