Table component is not keyboard accessible

[kyleoliveiro]

Sortable table header cells and clickable table rows cannot be interacted with via a keyboard, as they do not have the necessary tabindex attribute.

This issue also applies to the following components. Not sure whether to create a separate issue for each, so I'll list them here for now:

Components lacking keyboard accessbility

• Alert (dismiss button)
• Tag
• Tooltip
• Dialog (cannot access dialog contents)
• Resource list (only action buttons are accessible)

Thanks @kyleoliveiro ! We are planning to add keyboard accessibility to all, but Table seems like a good start.

I would like to tackle this if possible @landitus! :) Just to make sure i understood, both table header cells and table rows, should have the tabIndex set in order for them to be focusable by keyboard, is that right?
