Usage

Warning

Ensure that the table follows the recommendations on the accessibility tab so that the table works with assistive technology.

Title

Specify the title of the table using a caption element.

<rh-table>
  <table>
    <caption>
      Concerts
    </caption>
    <!-- ...table data -->
  </table>
</rh-table>

Column highlighting

To enable column highlighting, the table element must also include a col element for each column in the table, typically wrapped with a colgroup.

<rh-table>
  <table>
    <caption>
      Concerts
    </caption>
    <colgroup>
      <col>
      <col>
      <col>
    </colgroup>
    <!-- ...table with three columns -->
  </table>
</rh-table>

Sorting

To enable sorting on a column, add an rh-sort-button as the last child of the th cell.

<rh-table>
  <table>
    <caption>
      Concerts
    </caption>
    <colgroup>
      <col>
      <col>
      <col>
    </colgroup>
    <thead>
      <tr>
        <th id="concerts-date" scope="col" data-label="Date">Date</th>
        <th id="concerts-event" scope="col" data-label="Event">Event<rh-sort-button></rh-sort-button></th>
        <th id="concerts-venue" scope="col" data-label="Venue">Venue<rh-sort-button></rh-sort-button></th>
      </tr>
    </thead>
    <!-- ...table data sortable by Event and Venue -->
  </table>
</rh-table>

Summary

Additional information about the data in the table should be slotted into the summary slot after the table element.

    <colgroup>
