Таблица с объединенными ячейками, мультииндексом и переносом текста

Question

Мне бы хотелось иметь такой стол.Вотссылка для открытия изображения в другой вкладке.

Для меня важна структура. Форматирование нужно только для того, чтобы показать, что я хочу выделить из остального каким-то образом.

Как мне:

1. Убедитесь, что текст переносится, если данные превышают определенную длину.
2. Использовать многоколоночный формат для ячеек в правом нижнем углу, как показано на изображении?

Вот что у меня есть:

\documentclass[11pt]{article}
\usepackage{multirow}
\begin{document}
 % Text data placeholder. May be long enough that it needs to be wrapped.
\begin{table}[ht]
    \begin{center}
        \begin{tabular}{cccc}
            \hline
            \multirow{2}{*}{Outer index 1} & Inner index 1.1 & Text data placeholder. May be long enough that it needs to be wrapped. & Text data placeholder. May be long enough that it needs to be wrapped.\\
            & Inner index 1.2 & Text data placeholder. May be long enough that it needs to be wrapped. & Text data placeholder. May be long enough that it needs to be wrapped.\\ 
            \hline
            \multirow{2}{*}{Outer index 2} & Inner index 2.1 & Text data placeholder. May be long enough that it needs to be wrapped. & Text data placeholder. May be long enough that it needs to be wrapped.\\
            & Inner index 2.2 & Text data placeholder. May be long enough that it needs to be wrapped. & Text data placeholder. May be long enough that it needs to be wrapped.\\
            \hline
            \multirow{6}{*}{Outer index 3} &  Inner index 3.1 & Text data placeholder. May be long enough that it needs to be wrapped. & Text data placeholder. May be long enough that it needs to be wrapped.\\
            &Inner index 3.2 & Text data placeholder. May be long enough that it needs to be wrapped. & Text data placeholder. May be long enough that it needs to be wrapped.\\
            &Inner index 3.3 & Text data placeholder. May be long enough that it needs to be wrapped. & Text data placeholder. May be long enough that it needs to be wrapped.\\
            &Inner index 3.4 & Text data placeholder. May be long enough that it needs to be wrapped. & Text data placeholder. May be long enough that it needs to be wrapped.\\
            &Inner index 3.5 & Text data placeholder. May be long enough that it needs to be wrapped. & Text data placeholder. May be long enough that it needs to be wrapped.\\
            &Inner index 3.5 & Text data placeholder. May be long enough that it needs to be wrapped. & Text data placeholder. May be long enough that it needs to be wrapped.\\
            &Inner index 3.6 & Text data placeholder. May be long enough that it needs to be wrapped. & Text data placeholder. May be long enough that it needs to be wrapped.\\
            \hline
        \end{tabular}
    \end{center}
\end{table}

\end{document}

Лучшее форматирование приветствуется. Не стесняйтесь добавлять свои штрихи.

Answer 1

Включает следующее:

• tabularxдля Xстолбцов типа и таблицы, которая соответствует ширине текста
• \multicolumn для ячеек, охватывающих 2 столбца
• скорректированные значения \multirowдля вертикального центрирования текста в первом столбце
• заменено centerокружение, \centeringпоскольку прежнее добавляет дополнительное пустое пространство вокруг таблицы

• booktabsДля улучшения интервалов использованы горизонтальные линии из упаковки.

  \documentclass[11pt]{article}
  
  \usepackage{multirow}
  \usepackage{geometry}
  \usepackage{tabularx}
  \usepackage{booktabs}
  \usepackage{ragged2e}
  \begin{document}
  
  \begin{table}[ht]
      \centering
          \begin{tabularx}{\textwidth}{cc>{\RaggedRight\arraybackslash}X>{\RaggedRight\arraybackslash}X}
              \toprule
              \multirow{6}{*}{Outer index 1} & Inner index 1.1 & Text data placeholder. May be long enough that it needs to be wrapped. & Text data placeholder. May be long enough that it needs to be wrapped.\\
              & Inner index 1.2 & Text data placeholder. May be long enough that it needs to be wrapped. & Text data placeholder. May be long enough that it needs to be wrapped.\\ 
              \midrule
              \multirow{6}{*}{Outer index 2} & Inner index 2.1 & Text data placeholder. May be long enough that it needs to be wrapped. & Text data placeholder. May be long enough that it needs to be wrapped.\\

              \midrule

              \bottomrule
          \end{tabularx}
  \end{table}

Здесь я также использовал multirowдля содержимого второго столбца:

\documentclass[11pt]{article}

\usepackage{multirow}
\usepackage{geometry}
\usepackage{tabularx}
\usepackage{booktabs}
\usepackage{ragged2e}
\begin{document}

\begin{table}[ht]
    \centering
        \begin{tabularx}{\textwidth}{cc>{\RaggedRight\arraybackslash}X>{\RaggedRight\arraybackslash}X}
            \toprule
            \multirow{6}{*}{Outer index 1} & \multirow{3}{*}{Inner index 1.1} & Text data placeholder. May be long enough that it needs to be wrapped. & Text data placeholder. May be long enough that it needs to be wrapped.\\
            & \multirow{3}{*}{Inner index 1.2} & Text data placeholder. May be long enough that it needs to be wrapped. & Text data placeholder. May be long enough that it needs to be wrapped.\\ 
            \midrule
            \multirow{6}{*}{Outer index 2} & \multirow{3}{*}{Inner index 2.1} & Text data placeholder. May be long enough that it needs to be wrapped. & Text data placeholder. May be long enough that it needs to be wrapped.\\
            & \multirow{3}{*}{Inner index 2.2} & Text data placeholder. May be long enough that it needs to be wrapped. & Text data placeholder. May be long enough that it needs to be wrapped.\\
            \midrule
            \multirow{9}{*}{Outer index 3} &  \multirow{3}{*}{Inner index 3.1} & Text data placeholder. May be long enough that it needs to be wrapped. & Text data placeholder. May be long enough that it needs to be wrapped.\\
            & \multirow{3}{*}{Inner index 3.2} & \multicolumn{2}{>{\hsize=\dimexpr2\hsize+2\tabcolsep+\arrayrulewidth\relax\RaggedRight\arraybackslash}X}{Text data placeholder. May be long enough that it needs to be wrapped.  Text data placeholder. May be long enough that it needs to be wrapped.}\\
            & \multirow{3}{*}{Inner index 3.3} & \multicolumn{2}{>{\hsize=\dimexpr2\hsize+2\tabcolsep+\arrayrulewidth\relax\RaggedRight\arraybackslash}X}{ Text data placeholder. May be long enough that it needs to be wrapped.  Text data placeholder. May be long enough that it needs to be wrapped.}\\
            \bottomrule
        \end{tabularx}
\end{table}

\end{document}

Чтобы выровнять текст во втором столбце по вертикали, можно также использовать пакет makecellв сочетании с вертикально центрированными Xстолбцами, как показано в следующем примере MWE:

\documentclass[11pt]{article}

\usepackage{multirow}
\usepackage{geometry}
\usepackage{tabularx}
\usepackage{booktabs}
\usepackage{ragged2e}
\usepackage{makecell}
\renewcommand{\tabularxcolumn}[1]{m{#1}}
\begin{document}

\begin{table}[ht]
    \centering
        \begin{tabularx}{\textwidth}{cc>{\RaggedRight\arraybackslash}X>{\RaggedRight\arraybackslash}X}
            \toprule
            \multirow{6}{*}{Outer index 1} & \makecell[cc]{Inner index 1.1} & Text data placeholder. May be long enough that it needs to be wrapped. & Text data placeholder. May be long enough that it needs to be wrapped.\\
            & \makecell[cc]{Inner index 1.2} & Text data placeholder. May be long enough that it needs to be wrapped. & Text data placeholder. May be long enough that it needs to be wrapped.\\ 
            \midrule
            \multirow{6}{*}{Outer index 2} & \makecell[cc]{Inner index 2.1} & Text data placeholder. May be long enough that it needs to be wrapped. & Text data placeholder. May be long enough that it needs to be wrapped.\\
            & \makecell[cc]{Inner index 2.2} & Text data placeholder. May be long enough that it needs to be wrapped. & Text data placeholder. May be long enough that it needs to be wrapped.\\
            \midrule
            \multirow{9}{*}{Outer index 3} &  \makecell[cc]{Inner index 3.1} & Text data placeholder. May be long enough that it needs to be wrapped. & Text data placeholder. May be long enough that it needs to be wrapped.\\
            & \makecell[cc]{Inner index 3.2} & \multicolumn{2}{>{\hsize=\dimexpr2\hsize+2\tabcolsep+\arrayrulewidth\relax\RaggedRight\arraybackslash}X}{Text data placeholder. May be long enough that it needs to be wrapped.  Text data placeholder. May be long enough that it needs to be wrapped.}\\
            & \makecell[cc]{Inner index 3.3} & \multicolumn{2}{>{\hsize=\dimexpr2\hsize+2\tabcolsep+\arrayrulewidth\relax\RaggedRight\arraybackslash}X}{ Text data placeholder. May be long enough that it needs to be wrapped.  Text data placeholder. May be long enough that it needs to be wrapped.}\\
            \bottomrule
        \end{tabularx}
\end{table}
