Rules

“Rules” refer to success criteria in WCAG 2.0, checkpoints in WCAG 1.0 and similar requirements.

Primary Rules

The test case fails the following success criterion at line 7, column 5: http://www.w3.org/TR/2006/WD-WCAG20-20060427/guidelines.html#content-structure-separation-sequence.

Functional Outcome

The meaning is changed when the layout table is linearized.

Technical Comment

The sequence in which the cell contents appear in document order is different from the order in which the words are presented on screen. So linearizing the layout table changes the meaning.

This test case maps to failure F49: Failure of SC 1.3.3 due to changing the meaning of content by positioning information with HTML layout tables (http://www.w3.org/TR/2006/WD-WCAG20-TECHS-20060427/Overview.html#F49).
