/**
 * Grouped table (project, Suomen Jättikasvisyhdistys): a core table whose
 * first column names the group on the group's first row only, such as the
 * competition list (Ryhmä | Kasvi | Sarjat | Merkinnät on /kilpailu/). One
 * table is easy to update every year. A row that starts a group gets a
 * stronger line above it; on phones the rows stack: the group as a small
 * heading, the plant with its marks, then its classes.
 *
 * className: grouped-table (core/table, Additional CSS class)
 *
 * Structure:
 *   figure.wp-block-table.grouped-table > table
 *     thead > tr > th ×4
 *     tbody > tr > td ×4   td:first-child = the group, empty on its other rows
 *
 * Front end and editor. The table may be wider than a reading column, so it
 * keeps to --grouped-table-width.
