Tento fazer a próxima tabela com esta hachura, linhas tracejadas de células e chaves em Latex:
Já vi muitos exemplos diferentes neste site:Defina o fundo da tabela hachurado e sombreado usando tikz(eclosão),Tabelas com células coloridas e linhas tracejadas(linhas tracejadas de células),Como misturar coloração e hachura na mesma célula em um ambiente tabular?(eclosão+coloração).
Mas não encontrei células de hachura com ambos os tipos de hachura (nordeste + noroeste) e combinações inteiras de recursos, o que é necessário no meu exemplo.

Nos locais onde é necessário aquecimento duplo coloquei símbolo do infinito, mas é melhor olhar na foto acima.
PS: Desculpe pelo meu inglês. Não é bom o suficiente.

Proponho uma solução baseada em tabularx, bigdelime pstricks-add
A ideia geral é definir nós vazios nas células relevantes, deslocados para o canto inferior esquerdo da célula a que pertence, e depois ligar essas células por caminhos poligonais fechados, que são preenchidos com um dos estilos de preenchimento de hachura.
