A table caption can be used to provide a heading for the table as a hole. This is not required to meet WCAG 2.0, but is considered best practice because the <caption> element is explicitly associated with the table. The <caption> value should be a succinct description of the content of the table.
Examples on the Header cells page use other ways to introduce tables, but this and all other pages in this tutorial apply the <caption> element to tables.
Example 1: <caption> used as a table heading
This example has the table heading marked up using the <caption> element, its value "Concert dates" tells users what information the table contains.
|12 Feb||Waltz with Strauss||Main Hall|
|24 Mar||The Obelisks||West Wing|
|14 Apr||The What||Main Hall|
<caption> Concert dates </caption>
