Eu tenho que sincronizar a rolagem horizontal de tabelas. As colunas seriam as mesmas propriedades que podem ser alteradas para as colunas. Agora, o código a seguir mostra três tabelas com rolagem sincronizada. Mas quando eu altero o tamanho de qualquer coluna em qualquer uma das tabelas e, em seguida, tento rolar, recebo um erro de estouro de pilha e o gui é distorcido.

Eu estou tentando alcançá-lo, definindo a posição da janela de exibição do restante das tabelas para a coluna que vem primeiro no lado esquerdo. Se o tamanho das colunas for diferente, então, a partir da porcentagem rolada para essa coluna, estou reconstruindo a posição de outra tabela.
