Título da coluna na segunda linha

Título da coluna na segunda linha

Estou construindo uma tabela de resultados na qual gostaria que os títulos das colunas formados por uma linha (como a primeira e as duas últimas) estivessem alinhados com a segunda linha de títulos formados por duas linhas.

Sei que não fui claro então vou colocar um exemplo do que gostaria de obter:

Quero que "Resultado", "Bandiwdth" e "N" estejam imediatamente acima da linha, pois estão alinhados com a segunda linha de títulos de colunas de várias linhas.

Meu código é o seguinte:

Eu gostaria de desencorajá-lo fortemente de usar \adjustboxpara fazer o material tabular "caber" dentro do bloco de texto: isso provavelmente gerará caracteres extremamente pequenos e quase ilegíveis dentro da tabela. Dito de outra forma: não use, \adjustboxa menos que queira sinalizar aos seus leitores que você realmente não se importa se eles tentarão ler o conteúdo da tabela.

Em vez disso, sugiro que você aprenda como aproveitar o tabularxmeio ambiente. No código a seguir, combino um tabularxambiente com as facilidades do dcolumnpacote para que os dados numéricos fiquem alinhados em seus respectivos marcadores decimais. E use as macros de desenho de linha da booktabsmacro para gerar linhas horizontais bem espaçadas.

Falando por mim mesmo, eu não moveria as palavras “Resultado”, “Largura de banda” e “N” uma linha abaixo. Porém, se achar que isso é realmente necessário, basta inserir as instruções \renewcommand{\tabularxcolumn}[1]{b{#1}}após carregar o tabularxpacote.

A captura de tela a seguir mostra a tabela que incorpora as modificações sugeridas, seguida pelo código da tabela original que usa \adjustboxpara encaixar o material na largura do bloco de texto. Espero que você concorde que a tabela superior é mais legível. :-)

Você pode obter facilmente o que deseja com o \theadcomando from makecell. Adicionei algumas melhorias na sua tabela, usando o Stipo de coluna from siunitse booktabs. Removi o \adjustboxcomando, que normalmente não deveria ser usado com tabelas:
