An XHTML file that is well-formed but not valid because the tbody element appears before the thead element in the table instead of after it. It is not clear how assistive technology responds to this; possibly, the table heading is still read before the content of the table. Validity error: table body before table heading Christophe.Strobbe@esat.kuleuven.be en Copyright BenToWeb 2004-2007 2005-10-05 accepted for end user evaluation Strictly Conforming Documents

This test case is intended to fail because the table heading (thead) does not appear in its correct place in the markup. It is not clear if this causes problems for assistive technologies.

Were the column headers read to you before the content of the table?

If not, what happened?

Depending on the browser or assistive technology, the user may not be able to access the column headers before the table content.
