RGAA 3.2016 - Rule 5.6.2

Summary

This test consists in checking whether each row header of a data table is defined with a <th> tag.

To do so, we detect the tables on the page, and let the user make the control manually.

Description

Pour chaque tableau de données (balise table), chaque en-tête de lignes a-t-il une balise th ?

Level

A

Technical description

Scope

Page

Decision level

Semi-Decidable

Algorithm

Selection

Set1 (table tags identified as data 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.

Set2 (table tags not identified as data table from html markers)

All the <table> tags without an "id" attribute or a "class" attribute equal to the value of the "DATA_TABLE_MARKER" parameter or the "PRESENTATION_TABLE_MARKER" parameter or the "COMPLEX_TABLE_MARKER" parameter associated with the audit. That means select all the table tags of the page when the parameter is empty.

Process

Test1

For each occurence of Set1, raise a MessageA

Test2

For each occurence of Set2, raise a MessageB

MessageA : Check the usage of headers for data tables
  • code :CheckUsageOfHeaderForDataTable
  • status: Pre-Qualified
  • parameter : snippet
  • present in source : yes
MessageB : Check the nature of table and the usage of headers for data tables
  • code :CheckNatureOfTableAndUsageOfHeaders
  • status: Pre-Qualified
  • parameter : snippet
  • present in source : yes

Analysis

Not Applicable

The page has no <table> tag or only tables identified as presentation table (Set1 AND Set2 are empty)

Pre-Qualified

In all others 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.
