I've just read an article on table accessibility. It can not be that hard to build an accessible table, it's just the table
element including other th
, tr
and td
elements, right?
The article goes into beautiful detail on what it means to build an accessible table. In the first few paragraphs of it, it already included something that was new to me – the caption
table element.
<table>
<caption>Populations of cities</caption>
<thead>
<tr>
<th>City</th>
<th>Population</th>
</tr>
</thead>
<tr>
<!-- ... -->
</tr>
</table>
caption
is one element you don't see "in the wild" very often. The spec defines it as follows:
[...] the first element child of a table element.
The caption element represents the title of the table that is its parent, if it has a parent and that is a table element.
Defining a title and some additional information for a table makes total sense, and more surprising than its rare usage is only that the caption
element even has its own mention in the techniques for WCAG 2.0. 😲
My next table
will definitely include a caption
element.
