Summary
This test consists in checking whether each cell associated with one or several headers is well-defined.
To do so, we detect the tables on the page, and let the user make the control manually.

Criterion
Test
Description
Does each cell (td or th tag) associated with one or several headers with an id attribute meet the following conditions? The cell has a headers attribute
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 AND with <th> child tags OR with <td> 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
use through the “PRESENTATION_TABLE_MARKER” parameter or the
“DATA_TABLE_MARKER” parameter or the “COMPLEX_TABLE_MARKER” parameter AND with <th> child tags OR with <td> 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 <td> 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.
