Some data tables must have an accessible description (e.g. summary) of contents of the table.
Complex data tables are defined as tables with row and/or column spans, or more than one header cell (e.g. th element) in any row or column of the table.
An accessible description providing a summary of the organization of the table or numerical values reduces the time for users of assistive technology to explore and understand the content of a table.
An accessible description that includes a synopsis of the authors intended conclusions of viewing the content of a table make it easier for people using assistive technologies to understand importance of why the author provided the data table.
Information about the element associated with the result.
The information typically includes the tag name, accessible name or other information related to the rule requirements.
"Page" means that the result applied to the page. For example, the rule "One main landmark on the page" is a page level rule.
The element position is based on the DOM order of elements in the page.
The element position maybe useful in helping to locate a specific element on the page evaluated (e.g smaller numbers are typically toward the beginning of a page and larger numbers typically toward the end of a page).
Element position 1 is the first element.
The highest element position is the last element.
Element position values for most rule/page results will not be consecutive since a rule only applies to a sub set of elements found on a page.
