Problema de formatação tabular

Question

Estou tendo problemas para recriar a seguinte tabela em LaTeX:

(Observe que na primeira coluna, "Ação" está centralizada enquanto as linhas abaixo dela estão alinhadas à esquerda.) O mais próximo que cheguei foi este:

 \documentclass[12pt,oneside,letterpaper]{book}

  \usepackage{array}
  \usepackage{multirow}

  \begin{document}

 \begin{tabular}{|l|
 >{\centering\arraybackslash}p{0.75in}|  % this centers over multiple lines
 >{\centering\arraybackslash}p{0.75in}|
 >{\centering\arraybackslash}p{1.1in}|
 >{\centering\arraybackslash}p{1.1in}|
 >{\centering\arraybackslash}p{1.1in}|}
 \hline 
 \multicolumn{1}{|c|}{Action} % Fake multicol centers action
 & \multicolumn{2}{|c|}{Magnetic Flux}  % Merge two columns
 & \multirow{2}{1.1in}{\centering Direction of \\ Induced $B$ \\ Field  (Expected)} % Multirow seems not to be working?
 & \multirow{2}{1.1in}{\centering Expected Direction of Induced Current (CW/CCW)}
 & \multirow{2}{1.1in}{\centering Actual Direction of Induced Current } \\ 
 \hline 
 & Direction (Up/Down) & Increasing/ Decreasing &&& \\ % This row isn't behaving right
 \hline
 N pole in & & & & & \\ \hline 
 N pole out & & & & & \\ \hline
 S pole in & & & & & \\ \hline 
 S pole out & & & & & \\ \hline
 \end{tabular} 
 \end{document}

que produz esta tabela:

Parece que o multirow não está funcionando bem com a maneira como as coisas se estendem por várias colunas? E como estou usando um multicol "falso" para centralizar a ação, estou tendo problemas para estendê-lo por várias linhas.

Qualquer ajuda seria muito apreciada! Obrigado!

EDIT: Estou executando no Mac e compilando com pdfTeX 3.14159265-2.6-1.40.20 (TeX Live 2019) e SIM, recebo a tabela mostrada. Se as pessoas obtiverem uma tabela diferente, elas poderão mostrar o que obtiveram, com qual compilador? Eu adicionei \begin{document} e \end{document} junto com a classe do documento. Este é o arquivo completo que estou compilando.

Answer 1

Suponho que você esteja procurando o seguinte:

\documentclass[a4paper]{article}
\usepackage{geometry}
\usepackage{array, makecell, multirow}
\newcolumntype{P}[1]{>{\centering\arraybackslash}p{#1}}
\setcellgapes{3pt}
\makegapedcells

\begin{document}
 \begin{tabular}{|l| P{0.75in}|  
                     P{0.75in}|
                     P{1 in}|
                     P{1.2 in}|
                     P{1 in}|}
    \hline
\multirow{4}{*}{Action}
    & \multicolumn{2}{c|}{Magnetic Flux}    &   &   &   \\
    \cline{2-3}
    & \makecell{Direction\\ (Up/Down)}
        & \makecell{Increasing/\\ Decreasing}
            & \multirow{-2.8}{=}{\centering Direction of Induced $B$ Field  (Expected)}
                & \multirow{-2.8}{=}{\centering Expected Direction of Induced Current (CW/CCW)}
                    & \multirow{-2.8}{=}{\centering Actual Direction of Induced Current}   \\
 \hline
 N pole in  & & & & & \\ \hline
 N pole out & & & & & \\ \hline
 S pole in  & & & & & \\ \hline
 S pole out & & & & & \\ \hline
 \end{tabular}
 \end{document}

Answer 2

Incluí o código para dois calstables, digitado com a ajuda do pacotechamadas.

A primeira tabela é composta com réguas verticais. Devido à largura dos cabeçalhos, reduzi as margens com a ajuda degeometria.

Alinhei os cabeçalhos da segunda linha na parte inferior das células, o conteúdo de todas as outras células está centralizado verticalmente. Além disso, o tamanho da fonte usada no cabeçalho é reduzido, tornando-os menos dominantes e perturbadores.

A segunda calstableé composta sem réguas verticais. Como você descobrirá, eles são desnecessários para a legibilidade.

\documentclass[12pt,oneside,letterpaper]{book}
\usepackage{lmodern, cals}
\usepackage[left=3cm, right=3cm]{geometry}

\def\cals@AtBeginCell{\vfil}            % All cell contents vertically centred

% Shorthands for spanning cells

\let\sc=\spancontent

\def\rb{\ifx\cals@borderR\relax     % Right Border (rules) switch (off-on)

Answer 3

Você pode fazer isso facilmente tabular com {NiceTabular}of nicematrix.

Em {NiceTabular}, você mescla células horizontalmente e verticalmente com o comando \Block. Para as linhas, você fornece o número delógicolinhas (e não o número de linhas físicas como em \multicolumn).

Com a chave hvlines, todas as regras são sorteadas, exceto nos blocos (construídos por \Block).

\documentclass[a4paper]{article}
\usepackage{geometry}
\usepackage{nicematrix}

\begin{document}

\begin{NiceTabular}{lccccc}[hvlines,cell-space-limits=3pt]
\Block[c]{2-1}{Action} 
  & \Block{1-2}{Magnetic Flux} 
    & 
      & \Block{2-1}{Direction of\\ Induced $B$ Field\\ (Expected)}
        & \Block{2-1}{Expected Direction\\ of Induced Current\\ (CW/CCW)}
          & \Block{2-1}{Actual\\ Direction of\\ Induced Current} \\
& \Block{}{Direction\\ (Up/Down)} & \Block{}{Increasing/\\ Decreasing} \\
N pole in  \\ 
N pole out \\ 
S pole in  \\ 
S pole out \\ 
\end{NiceTabular}

\end{document}

Você precisa de várias compilações (porque nicematrixusa nós PGF/Tikz nos bastidores).
