table – Latex – Como mesclar colunas de forma a corrigir erro de espaçamento na última coluna da tabela?


Olá! Estou tentando mesclar a terceira coluna da tabela do código em anexo mas não estou conseguindo desenvolver um código que possa eliminar o erro de espaçamento na última coluna. Observe que o texto da terceira coluna se alinha com o da última coluna, provocando um espaçamento que prejudica a estética da tabela. Se fosse no Excel seria muito simples pois simplesmente mesclaria as linhas da terceira coluna e resolveria o problema. Alguém poderia me ajudar nesta correção do código por favor?
