LaTex表格内单元格内容强制换行

\newcommand{\tabincell}[2]{\begin{tabular}{@{}#1@{}}#2\end{tabular}}%放在导言区

%然后使用&\tabincell{c}{}&就可以在表格中自动换行

%比如这么用

\begin{tabular}{|c|c|}

\hline

1 & the first line //

\hline

2 & /tabincell{c}{haha// heihei//zeze} //

\hline

\end{tabular}

以下为一例子，可直接存为.tex文件编译运行:

\documentclass[a4paper,12pt]{article}

\begin{document}

\begin{table}

\newcommand{\tabincell}[2]{\begin{tabular}{@{}#1@{}}#2\end{tabular}}

  \centering

  \begin{tabular}{|c|c|c|}\hline

1 & \tabincell{c}{the first line \\ the next\\the next\\ last} & \tabincell{c}{one \\ one}\\\hline

2 & \tabincell{c}{hello\\ aha\\ ok \\yes \\en}
& \tabincell{c}{two \\ two \\ two} \\\hline

\end{tabular}

  \caption{longtitle}

\end{table}

\end{document}
