表格内换行,同时保持自动换行

表格内换行,同时保持自动换行

我声明了一个这样的宏:

\newcommand{\itemcell}[1]{%
    \begin{tabular}[t]{@{}l@{}}#1\end{tabular}
} 

然而,我现在正在为此苦苦挣扎,因为它不再允许自动换行。请参见以下示例:

\begin{longtable}{p{4cm}p{1.5cm}p{1.2cm}p{1.2cm}p{1.2cm}p{\dimexpr\columnwidth-9.1cm-12\tabcolsep\relax}}
\toprule
Title 1 & Title 2 & Title 3 & Title 4 & Title 5 & Title 6 \\
\midrule
a       & b       & c       & d       & e       & \itemcell{This is a very long description which won't fit in 1 line, it should break, but it won't\\And this is a second line} \\
\bottomrule
\end{longtable}

的内容\itemcell{}不会在列尾换行,超出范围hbox则会传入。

我该如何安排这个宏来恢复默认行为?

答案1

p列允许换行,因此根本不需要宏,只需使用

\begin{longtable}{p{4cm}p{1.5cm}p{1.2cm}p{1.2cm}p{1.2cm}p{\dimexpr\columnwidth-9.1cm-12\tabcolsep\relax}}
\toprule
Title 1 & Title 2 & Title 3 & Title 4 & Title 5 & Title 6 \\
\midrule
a       & b       & c       & d       & e       &
This is a very long description which won't fit in 1 line, it should break, but it won't

And this is a second line\\
\bottomrule
\end{longtable}

在一c列中,您可以在本地使用嵌套表格来允许多行手动换行,但您的定义添加了虚假的空白,因为它缺少%

\newcommand{\itemcell}[1]{%
    \begin{tabular}[t]{@{}l@{}}#1\end{tabular}%%%%
}
