Sub-components

• `` - Table head
• `` - Table body
• `` - Table row
• `` - Table header cell
• `` - Table data cell
• `` - Table caption

Requirements

• MUST implement PFv6 visual designs
• MUST provide end-user feature parity with `@patternfly/react-table` Table
• MAY adjust element API to leverage web platform strengths
• SHOULD maintain CSS custom property theming compatibility
• SHOULD expose useful CSS shadow parts

Element-specific considerations

• Source package: `@patternfly/react-table`, not `@patternfly/react-core`
• React uses a composable table model - `Th`/`Td` take props for sort, select, expand, actions. Web component approach can instead rely on standard `` semantics with CSS augmentation; avoid re-inventing table semantics
• React `sortBy`, `onSort` on `Th` - emit `sort` event from `pf-v6-th`; parent manages sort state
• Selectable rows: `Td` with `select={{ isSelected, onSelect }}` renders checkbox; manage selection state in parent
• Expandable rows: `Tr isExpanded`, `Td expand` - toggled via `pf-v6-tr expanded` attribute
• Compound expandable: multiple expand cells per row - complex; verify v6 scope
• Sticky header/columns: CSS `position: sticky` with JS-computed offsets - SSR-safe
• `ActionsColumn` in `Td` - floating action menu; integrates with ``
• `Caption` should use native `
` element
• ARIA: native `` semantics; `aria-sort` on sortable `
