We initially added all elements which have default tab-order to avoid potential violations. But `<a>` should be sufficient as it's the only potential option possible in API description. Link will only make table cell tabbable via keyboard. As CSS is adding overflow: auto on table cells, making cells to be tabbable. The proposed solution here makes table cells accessible via keyboard by adding tabindex.
