DataTable uses a <i>treegrid</i> element whose attributes can be extended with the <i>tableProps</i> option. This property allows passing aria roles and attributes like <i>aria-label</i> and <i>aria-describedby</i> to define the table for
|
|
readers. Default role of the table is <i>table</i>. Header, body and footer elements use <i>rowgroup</i>, rows use <i>row</i> role, header cells have <i>columnheader</i> and body cells use <i>cell</i> roles. Sortable headers utilizer
|
|
<i>aria-sort</i> attribute either set to "ascending" or "descending".
|
|
</p>
|
|
|
|
<p>Row elements manage <i>aria-expanded</i> for state along with <i>aria-posinset</i>, <i>aria-setsize</i> and <i>aria-level</i> attribute to define the hierachy.</p>
|
|
|
|
<p>When selection is enabled, <i>aria-selected</i> is set to true on a row. In checkbox mode, TreeTable component uses a hidden native checkbox element.</p>
|
|
|
|
<p>Editable cells use custom templating so you need to manage aria roles and attributes manually if required.</p>
|
|
|
|
<p>Paginator is a standalone component used inside the DataTable, refer to the <PrimeVueNuxtLink to="/paginator">paginator</PrimeVueNuxtLink> for more information about the accessibility features.</p>
