expect

header and body remain the same position when adding a column

Inizia con la riproduzione Demo fornita usando il componente Table, lo scorrimento orizzontale e l’azione di aggiunta di una colonna. Traccia come vengono gestite le posizioni di scorrimento dell’intestazione e del corpo quando cambiano le colonne, quindi verifica che l’aggiunta di una colonna lasci invariate entrambe le posizioni.
