如何垂直对齐表格单元格中的文本？

Question

以下是在 BibTxtMng 中创建表格的乳胶代码

 \begin{table}[!htbp]
 \centering
 \caption{Spanish Traffic Sign according to the color and shape \cite{Paper12}}
  \begin{tabular}{|>{\raggedright}p{3.1cm}|>{\raggedright}p{3.1cm}|>
   {\raggedright}p{3.1cm}|}
   \hline
   Color          & Shape    & Meaning \tabularnewline
   \hline
    Red Rim        & Circle   & Prohibition\tabularnewline
    \hline
    Red Rim (Up)   & Triangle & Danger      \tabularnewline
    \hline
     Red Rim (Down) & Triangle & Yield       \tabularnewline
    \hline
        Red            & Octagonal & Stop\tabularnewline
    \hline
      Blue  & Square &  Recommendation \tabularnewline
       \hline
      Blue &    Circle &    Obligation \tabularnewline
     \hline
     White  & Circle    & End of Prohibition \tabularnewline
     \hline
    Yellow & Circle & End of Prohibition (construction)\tabularnewline
      \hline
       \end{tabular}
       \label{Spanish_TS}
       \end{table}

这是我得到的输出表

我希望黄色和圆形的文字（最后一行）位于垂直方向的中心。不要像那样放在顶部。

怎么做？？

Answer 1

您可以将m列说明符用于最后一行的最后一个单元格。

\documentclass{article}
\usepackage{array}             %% you need this
\begin{document}
   \begin{table}[!htbp]
 \centering
 \caption{Spanish Traffic Sign according to the color and shape \cite{Paper12}}
  \begin{tabular}{|>{\raggedright}p{3.1cm}|>{\raggedright}p{3.1cm}|>
   {\raggedright}p{3.1cm}|}
   \hline
   Color          & Shape    & Meaning \tabularnewline
   \hline
    Red Rim        & Circle   & Prohibition\tabularnewline
    \hline
    Red Rim (Up)   & Triangle & Danger      \tabularnewline
    \hline
     Red Rim (Down) & Triangle & Yield       \tabularnewline
    \hline
        Red            & Octagonal & Stop\tabularnewline
    \hline
      Blue  & Square &  Recommendation \tabularnewline
       \hline
      Blue &    Circle &    Obligation \tabularnewline
     \hline
     White  & Circle    & End of Prohibition \tabularnewline
     \hline
    Yellow & Circle & \multicolumn{1}{|m{3.1cm}|}{End of Prohibition (construction)}\tabularnewline
      \hline
       \end{tabular}
       \label{Spanish_TS}
       \end{table}
\end{document}

m如果列中有可变宽度的文本，则可以对所有列使用列说明符以实现垂直对齐。

Answer 2

如果您愿意自己手动在行内进行换行，则可以使用\Centerstack，如下所示。但是在这种情况下，p除非您想要它们的宽度，否则实际上不需要列。您可以通过删除该声明并取消注释我的代码中的其他 3 行来省去它们。

\documentclass{article}
\usepackage{array}
\usepackage[usestackEOL]{stackengine}
%\edef\tmp{\the\baselineskip}
%\setstackgap{L}{\tmp}
\begin{document}
   \begin{table}[!htbp]
 \centering
 \caption{Spanish Traffic Sign according to the color and shape \cite{Paper12}}
%\begin{tabular}{|l|l|l|}
  \begin{tabular}{|>{\raggedright}p{3.1cm}|>{\raggedright}p{3.1cm}|>{\raggedright}p{3.1cm}|}
   \hline
   Color          & Shape    & Meaning \tabularnewline
   \hline
    Red Rim        & Circle   & Prohibition\tabularnewline
    \hline
    Red Rim (Up)   & Triangle & Danger      \tabularnewline
    \hline
     Red Rim (Down) & Triangle & Yield       \tabularnewline
    \hline
        Red            & Octagonal & Stop\tabularnewline
    \hline
      Blue  & Square &  Recommendation \tabularnewline
       \hline
      Blue &    Circle &    Obligation \tabularnewline
     \hline
     White  & Circle    & End of Prohibition \tabularnewline
     \hline
    Yellow & Circle & \Centerstack[l]{End of\\ Prohibition\\ (construction)}\tabularnewline
      \hline
       \end{tabular}
       \label{Spanish_TS}
       \end{table}
\end{document}
