+While Tooltip content can be passed to any table header via the `tooltipInfo` prop, it is strong advised to avoid this if the header is not an interactive element as the tooltip content will be unreadable to keyboard users or those that use assistive technologies.

+### Expandable
+
+The `expandable` prop introduces known accessibility issues with nesting interactive elements as children of a `button` or `anchor` tag. We recommend avoiding this pattern if possible, or creating a tier 3 component that adheres to correct WCAG hierarchy.
