/**
 * Grouped table: a core table whose first column names the group on the
 * group's first row only, such as a price list or a competition list
 * (Ryhmä | Palvelu | Sisältää | Hinta). One table is easy to update, and a
 * row that starts a group gets a stronger line above it. On phones the rows
 * stack: the group as a small heading, the item with its note on the right,
 * then its details.
 *
 * className: grouped-table (core/table, Additional CSS class)
 *
 * Structure:
 *   figure.wp-block-table.grouped-table > table
 *     thead > tr > th ×4                 hidden on phones
 *     tbody > tr > td ×4
 *       td:first-child                   the group, empty on the group's other rows
 *       td:nth-child(2)                  the item (bold)
 *       td:nth-child(3)                  details (on phones under the item)
 *       td:nth-child(4)                  a short note such as a price (on phones
 *                                        right of the item); may be left out
 *
 * Tuning: --grouped-table-width (980px, the table may be wider than a
 *         reading column)
 *
 * Pages only: inside an article (.post-content) the article table style in
 * css/article.css loads later and wins.
 *
 * Front end and editor.
