使用p{width}作为列说明符，而不是l/r/c。

\begin{tabular}{|p{1cm}|p{3cm}|}
  This text will be wrapped & Some more text \\
\end{tabular}

编辑:(根据评论)

\begin{table}[ht]
    \centering
    \begin{tabular}{p{0.35\linewidth} | p{0.6\linewidth}}
      Column 1  & Column2 \\ \hline
      This text will be wrapped & Some more text \\
      Some text here & This text maybe wrapped here if its tooooo long \\
    \end{tabular}
    \caption{Caption}
    \label{tab:my_label}
\end{table}

我们得到:

 \caption{ Example of force text wrap}
 \begin{center}
  \begin{tabular}{|c|c|}
   \hline
   cell 1       &   cell 2 \\   \hline
   cell 3                &       cell 4 & & very big line that needs to be wrap. \\ \hline
   cell 5       &   cell 6 \\   \hline
  \end{tabular}
  \label{table:example}
 \end{center}
\end{table}

另一种选择是在每个需要文本换行的单元格中插入一个迷你页，例如:

\begin{table}[H]
\begin{tabular}{l}
\begin{minipage}[t]{0.8\columnwidth}%
a very long line a very long line a very long line a very long line
a very long line a very long line a very long line a very long line
a very long line a very long line a very long line %
\end{minipage}\tabularnewline
\end{tabular}
\end{table}

简单得像一块蛋糕!

你可以定义一个新的列类型，比如(L)，同时保持当前的对齐(c, r或L):

\documentclass{article}
\usepackage{array}
\newcolumntype{L}{>{\centering\arraybackslash}m{3cm}}

\begin{document}

\begin{table}
    \begin{tabular}{|c|L|L|}
        \hline
        Title 1 & Title 2 & Title 3 \\
        \hline 
        one-liner & multi-line and centered & \multicolumn{1}{m{3cm}|}{multi-line piece of text to show case a multi-line and justified cell}   \\
        \hline
        apple & orange & banana \\
        \hline
        apple & orange & banana \\
        \hline
    \end{tabular}
\end{table}
\end{document}

如果你想要包装你的文本，但保持对齐，那么你可以包装单元格在一个迷你页面或varwidth环境(varwidth来自varwidth包)。Varwidth将“与内容一样宽，但不超过X”。您可以创建一个自定义列类型，它的作用类似于“p{xx}”，但是使用

\newcolumntype{M}[1]{>{\begin{varwidth}[t]{#1}}l<{\end{varwidth}}}

这可能需要数组包。然后当你使用像\begin{tabular}{llM{2in}}这样的东西时，前两列我们是正常的左对齐，第三列将是正常的左对齐，但如果它超过2in，那么文本将被换行。
