Complex data table
This term is defined by more than one standard, and the wording differs. Each definition below is the one that applies to that standard’s criteria.
Definition in RAWeb 1.1
A data table is a structure introduced by a <table> tag or when it is correctly rendered by assistive technologies by a tag with a WAI-ARIA role="table" attribute.
When a data table contains headers that span multiple rows and/or columns of the grid, or whose scope is not valid for the entire column or row, it is referred to as a complex data table. It is then necessary to provide a "summary" to explain its nature and structure in order to make it easier to consult for users of assistive technologies, for example.
Definition in RAAM 1.1
When a data table contains headers that are not distributed solely over the first row and/or column of the grid, or whose scope does not apply to the entire column or row, it is referred to as a complex data table. It is then necessary to provide a "summary" to explain its nature and structure in order to make it easier to consult for users of assistive technologies, for example.
Definition in RAPDF 1.1
A complex data table is a table that contains more than one row and/or column header.
A complex data table cannot be rendered correctly when produced using office software.
