Data table

Tabular data in a real table: a caption that names it (hidden by default — a caption is the table's accessible name, not a title), headers scoped to their column, aria-sort on the sorted one, an opt-in row-header column, and a real tfoot for totals. It never sorts and never selects: onSortChange cycles unsorted → ascending → descending → unsorted and onSelectionChange reports intent, so a server-paginated table sorts on the server rather than reordering one page. Selection carries select-all with an indeterminate state, an announced count, and a type that requires a per-row label. rowHref make
