longtabu com multicolunas e multilinhas

Question

Usei o código proposto por @Zarko. Até agora, funciona, exceto para as multilinhas, que parecem sair do quadro da página, conforme ilustrado na captura de tela. Alguém tem uma ideia?

Também mudei longtabuo "premble" - remova regras duplicadas. O resultado mostrado é obtido após a segunda execução da compilação MWE.

Editar: Com meu MWE, agora preenchido com tabela inteira obtenho o resultado desejado e esperado:

Por favor, observe as diferenças entre o MWE proposto abaixo e o seu código em questão! Em meu MWE, coloquei um esforço significativo necessário para limpar seu código. Nele são removidas todas \multicolumnsas definições desnecessárias e redesenhadas para cabeçalhos e rodapés, alterações podem ser usadas incorretamente nas regras etc:

Observação: longtable(também longtabu) tente quebrar a tabela entre as páginas no início de novas linhas. No caso de usar multirowcélulas, longtableconsidere-as como uma linha, para que não possam ser quebradas entre páginas (sem alguma "magia negra" do autor do pacote, vejapergunta: É possível que uma célula com várias linhas seja dividida em páginas ao usar tabela longa).

Como nos meus testes do seu MWE em questão não reproduziu o problema relatado só posso concluir que você tem alguma "magia negra" no seu computador. Uma tentativa desesperada pode ser atualizar sua instalação do LeTeX ou testar seu MWE em algum outro computador ou com outro nome.

Answer 2

Por exemplo, \lipsum[3]antes da mesa, seu problema seria reproduzível.

Você pode evitar quebras de página após linhas tabulares usando \\*. No exemplo a seguir, as quebras de página são permitidas apenas nas regras.

(Em relação a um comentário em seuPostagem cruzada em golatex.de: Coloque \cellcolor{gray}chaves para alinhar os números nessas células também.)
