Code of conduct

• I agree to follow this project's code of conduct.

Impacted component(s)

sp-table

Expected behavior

Given the default role for sp-table is role="grid" I expect the component to support the keyboard navigation associated with the grid role.

ref: https://www.w3.org/WAI/ARIA/apg/patterns/grid/ see Keyboard Interaction For Data Grids section

Per @jnurthen, the default role should be table.

Actual behavior

Navigation between sortable column headers and cell which contain inputs is with tabs.

Yes, I can manually set role=table.
