The current spec says that <th> can have any role value: http://www.w3.org/html/wg/drafts/html/master/tabular-data.html#the-th-element But the spec only allows the aria-sort attribute for elements that have either role=columnheader or role=rowheader. So you need to something like this: <table role=grid> <tr role=row> <th role=columnheader style="font-weight: normal; width: 0px;" class="sorting_asc" tabindex="0" aria-controls="transfer-wizard_search_results_from" rowspan="1" colspan="1" aria-sort="ascending" aria-label="Tilinumero: activate to sort column ascending">foobar</th> ... If that doesn't solve your problem, please feel free to re-open this bug. 109162 2 craig 2014-07-22 13:12:02 +0000 Isn't the role implied: http://www.w3.org/TR/wai-aria/roles#columnheader Base Concept: HTML th[scope="col"] i.e. why take a th[scope="col"] and add a role of columnheader, when the role is already known. As far as I'm aware, the role attribute is for when incorrect HTML is being used, perhaps being generated by JS with spans? 109205 3 craig 2014-07-23 09:39:41 +0000 Ok, this is more of an issue that needs to be resolved with HTML than the validator: http://lists.w3.org/Archives/Public/www-validator/2014Jul/0014.html 128649 4 david100 2017-06-16 18:57:14 +0000 I filed a but against HTML. https://github.com/w3c/html/issues/909#issuecomment-308889446 Editor Steve Faulkner said that <th> does indeed have semantics as shown in the accessibility API mappings doc. https://w3c.github.io/html-aam/#el-th Therefore, this should pass the validator <th aria-sort="ascending" ...> It should not require a redundant aria role="columnheader"
