• Ensure that VisuallyHidden is imported at the top of this file; without the import, the component reference will break the build.

{direction === SortDirection.NONE ? <VisuallyHidden>sort ascending</VisuallyHidden> : null}

• [nitpick] Consider adding or updating a Storybook story or a snippet in the docs to demonstrate the new screen-reader-only text in action for accessibility previews.

DataTable: Add visually hidden text to sortable DataTable column buttons

[Copilot]

[nitpick] This assertion now ties the test to the exact hidden text string, which could be brittle; consider using a regex or querying by part of the name (e.g., /Column A.*ascending/) to make the test less coupled to implementation details.

Suggested change

	expect(getSortHeader('Column A sort ascending')).not.toHaveAttribute('aria-sort')
	expect(getSortHeader(/Column A.*ascending/)).not.toHaveAttribute('aria-sort')
