GridAccessibilityExtension Add-on

Accessibility extension for adding id attribute to V8 Grid headers and headers attribute to Grid cells

GridAccessibilityExtension is an accessibility extension that enables adding the id attribute to Vaadin 8 Grid table headers (<th>) and headers attribute to the cells (<td>).

Current limitations:

• The extension will not work correctly if columns are reordered. Column reordering is not allowed by default in Grid, so if has not been explicitly enabled, this won't be an issue.
• Header order – including empty headers – needs to be given to the extension as-is due to current limitations in Grid HeaderCell coupling with Columns and Cells

Comprehensive example for using this extension can be found in the DemoUI in GitHub.

Information on the accessibility standards this extension fulfills:

• Web Usability – Accessible Data Tables (2005)
• WC3 – H43: Using id and headers attributes to associate data cells with header cells in data tables
