Tables
Including the export-data module will enable viewing the chart as a data table. This module also requires the exporting module.
<script src="https://code.highcharts.com/modules/exporting.js"></script><script src="https://code.highcharts.com/modules/export-data.js"></script><script src="https://code.highcharts.com/modules/accessibility.js"></script>
Note that simply showing the chart data as a table is not considered a sufficient accessible alternative to a chart, and you should still enable the Accessibility module unless there is a specific reason not to do so.
See our data-module documentation article for more information on the data module and working with tables in Highcharts.
