防止表格中的标题连字

Question

如何才能防止tabulary环境连字表头？

也许重新定义\tyformat，但我找不到对该命令的任何引用。

根据评论所建议，我尝试：\newcolumntype{}

\documentclass{article}
\usepackage{tabulary}
\begin{document}

    \newcolumntype{Y}{>{\raggedright\arraybackslash}J}
    \begin{tabulary}{\textwidth}{YYYYY} 
      \hline
     & label 1 with much more text than is needed & label 2 is also very long & label 3 & label 4 \\ 
      \hline
    1 & item 1 & item 2 & item 3 & item 4 but again with too much text \\ 
      2 & A & B & C & D \\ 
       \hline
\end{tabulary}

\end{document}

不幸的是，第四列被连字符了，而我只想换行。我看不出普通列类型和{JJJJJ}自定义列类型有什么区别。

如果使用，\raggedright则仅当单词长度超过行宽时，LaTeX 才会进行连字符连接，因此您只需确保不会出现小得可笑的列。我tymin在这里设置为 1cm。请注意，您不需要Y为参差不齐的右列进行定义，因为本质上是相同内容的tabulary预定义。L

\documentclass{article}
\usepackage{tabulary}
\begin{document}

    \setlength\tymin{1cm}
    \noindent
    \begin{tabulary}{\textwidth}{LLLLL} 
      \hline
     & label 1 with much more text than is needed & label 2 is also very long & label 3 & label 4 \\ 
      \hline
    1 & item 1 & item 2 & item 3 & item 4 but again with too much text \\ 
      2 & A & B & C & D \\ 
       \hline
\end{tabulary}

\end{document}
