RGAA 3.0 - Rule 5.7.2
Summary
The test consists in detecting data or complex tables on the page.
Checking whether each header of a data table applied to the whole row or to the whole column uses an appropriate scope attribute has to be done manually.
Business description
Criterion
Test
Description
Does each header cell (th tag) applied to the whole row or the whole column and having a scope attribute meet one of the following conditions? The header has a scope attribute with the value “row” for row headers
Level
A
Technical description
Scope
Page
Decision level
Semi-Decidable
Algorithm
Selection
Set1 (table tags identified as data or complex table from html markers)
All the <table>
tags with an “id” attribute or a “class” attribute or a “role” attribute that matches one of the values set by the user through the “DATA_TABLE_MARKER” parameter or the “COMPLEX_TABLE_MARKER” parameter AND with <th>
child tags.
Set2 (table tags not identified as data table from html markers)
All the <table>
tags that don’t have an “id” attribute or a “class” attribute or a “role” attribute that matches one the values set by the user through the “PRESENTATION_TABLE_MARKER” parameter or the
“DATA_TABLE_MARKER” parameter or the “COMPLEX_TABLE_MARKER” parameter AND with <th>
child tags.
That means select all the <table>
tags of the page when these parameters are empty.
Process
Test1
For each occurence of Set1, raise a MessageA
Test2
For each occurence of Set2, raise a MessageB
MessageA : Check the definition of headers for data tables
- code :CheckDefinitionOfHeaderForDataTable
- status: Pre-Qualified
- parameter : snippet
- present in source : yes
MessageB : Check the nature of table and the definition of headers for data tables
- code :CheckNatureOfTableAndHeadersDefinition
- status: Pre-Qualified
- parameter : snippet
- present in source : yes
Analysis
Not Applicable
The page has no <table>
tag with <th>
child tags or only tables identified as presentation table (Set1 AND Set2 are empty)
Pre-Qualified
In all other cases
Notes
We only detect the elements of the scope of the test to determine whether the test is applicable.
Complex tables are seen as a subset of data tables. That’s tables identified as complex tables are added to the set of identified data tables.
