RGAA 3.0 - 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.

Business description

Criterion

5.6

Test

5.6.2

Description

For each data table (table tag), does each row header have a th tag?

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.
