Muszę zsynchronizować przewijanie w poziomie tabel. Kolumny byłyby tą samą właściwością, którą można zmienić, aby kolumny były ich rozmiarem. Teraz poniższy kod pokazuje 3 tabele z zsynchronizowanym przewijaniem. Ale gdy zmieniam rozmiar dowolnej kolumny w dowolnej tabeli, a następnie próbuję przewijać, otrzymuję błąd przepełnienia stosu i gui jest zniekształcony.

Próbuję to osiągnąć, ustawiając pozycję rzutni reszty tabel na kolumnę, która jest pierwsza po lewej stronie. Jeśli rozmiar kolumn jest inny, to od procentu przewiniętego dla tej kolumny odtwarzam pozycję innej tabeli.
