Gostaria de adicionar uma equação em uma célula com várias linhas, usando tabela e largura definida. Funcionou em todos os lugares da tabela, exceto em uma célula que é uma multilinha de duas outras multilinhas. Nesse caso, recebo um erro. (A célula está indicada AQUI na imagem anexa). Você tem alguma ideia de como resolver isso? Obrigado!

Como não tenho a DissOnlineLatexclasse document, usei o artigo a seguir.
Eu não colocaria equationambientes dentro de um tabularambiente e teria pensado que isso levaria a uma pilha de erros. Então, estou surpreso que você receba apenas um erro dentro das \multirowcélulas. Acho que isso funciona porque você está usando um Mtipo -column. Se você quiser colocar um equationambiente dentro da \multirowcélula, a coisa óbvia a fazer é colocar equationdentro de um minipageambiente. Usar isso parece fazer o que você deseja:
Definir a largura do minipageambiente \linbewidthdeveria, em teoria, fornecer a largura correta. Descobri por tentativa e erro que usar 0.97\linewidthfuncionou melhor porque fez com que o número da equação nesta célula se alinhasse corretamente com os outros números da equação. Aqui está o seu MWE modificado:
