  Fixierter Tabellenkopf nach dem Prinzip aus dem Beispiel:
  - Tabelle bleibt 100 % breit,
  - tbody ist der vertikal scrollbare Bereich,
  - die Zeilen werden als Flex-Reihen gerendert,
  - die Spalte description erhält bewusst deutlich mehr Breite,
  - die schmalen Spalten umbrechen, damit möglichst kein horizontaler Scroll entsteht.
