Re: Labels on Checkboxes in data tables

In addition to my statement that WAI-ARIA techniques have not reached the status of WCAG sufficient technique so far, I'd like to clarify that ARIA techniques may still be used to claim conformance provided that they have sufficient accessibility support.

Whether or not a technique has already been published in the informational resources of WCAG 2.0 is not the decisive criterion. Instead, whether or not a technique can be deemed sufficient will depend on the current level of support in the context of use of the site that includes it.

Some aria roles and properties properties are better supported than others across the spectrum of browsers & assistive technologies. In constrained environments (company intranets, for example) accessibility support may be demonstrated by showing that the particular set of OS, browser and screen reader deployed supports the technique used. For public internet sites, it is an open call whether the share of supporting browsers & AT is already high enough to declare a technique accessibility supported. We all know that the speed of updating technologies varies a lot across countries and institutions.

In a simple and very short table as provided in the example, doing without visible label may be OK even for low vision users. But if you think of a matrix with longer rows of checkboxes (like Likert scale ratings) in a huge multi-row table, there certainly wouldn't be enough visual context for low vision users using magnification software or text size cranked up.
