Longtabu 中奇怪的行距效果

Question

我得到了一些奇怪的效果longtabu：

正如你所看到的λ似乎更接近上面的线而不是下面的线。我不明白为什么……

这是我制作上述图片的代码：

\documentclass[
    fontsize=11pt,
]{scrbook}

\usepackage{xltxtra}

\usepackage{array}
\usepackage{tabu}
\usepackage{longtable}

\usepackage[osf]{libertine}

\begin{document}
    \begin{longtabu} to \textwidth {lX}
         \textbf{L} & Musica incantans sive poema exprimens musicae vires per illam juvene in insaniam
        acto et musici inde periculum. Authore Roberto South Art. Bac. ex Aede Christi. Oxonii, Typis
        Leon. Lichfield Academiae Typographi, Impensis Tho. Robinson. Anno 1655. \\ 
         \textbf{λ} & \textit{Überarbeitete, zweite Fassung des Gedichts zwischen 1655 und 1667.} \\ 
         \textbf{W} & Musica incantans sive poema exprimens musicae vires juvenem in insaniam adigentis et
        musici inde periculum. Authore Roberto South Art. Bac. ex Aede Christi. Oxonii, Typis W.\,H.,
        Impensis G. West. Anno Dom. 1667. \\ 
    \end{longtabu}%
\end{document}

解决方法是给λ线以使其更高。

Answer 1

看起来禁忌\strut忘记在单元格末尾添加 a X，因此

\begin{longtabu} to \textwidth {lX<{\strut}}

应该可以解决问题。

Answer 2

另一个解决方案是

\tabulinesep=1.2mm

在-环境之前longtabu。

\documentclass[
    fontsize=11pt,
]{scrbook}

\usepackage{xltxtra}

\usepackage{array, tabu, longtable}

\usepackage[osf]{libertine}

\begin{document}
\tabulinesep=1.3mm
    \begin{longtabu} to \textwidth {lX}
         \textbf{L} & Musica incantans sive poema exprimens musicae vires per illam juvene in insaniam
        acto et musici inde periculum. Authore Roberto South Art. Bac. ex Aede Christi. Oxonii, Typis
        Leon. Lichfield Academiae Typographi, Impensis Tho. Robinson. Anno 1655. \\ 
         \textbf{λ} & \textit{Überarbeitete, zweite Fassung des Gedichts zwischen 1655 und 1667.} \\ 
         \textbf{W} & Musica incantans sive poema exprimens musicae vires juvenem in insaniam adigentis et
        musici inde periculum. Authore Roberto South Art. Bac. ex Aede Christi. Oxonii, Typis W.\,H.,
        Impensis G. West. Anno Dom. 1667. \\ 
    \end{longtabu}

\end{document}

Answer 3

新的 LaTeX3 软件包tabularray是过时软件包的替代品tabu。您可以尝试以下longtblr环境：

\documentclass[fontsize=11pt,]{scrbook}

\usepackage{xltxtra}
\usepackage[osf]{libertine}

\usepackage{tabularray}
\SetTblrInner[longtblr]{rowsep=0pt}

\begin{document}

\begin{longtblr}[
  caption = {Long Caption},
]{colspec={lX},width=\linewidth,column{1}={font=\bfseries}}
  L & Musica incantans sive poema exprimens musicae vires per illam juvene in insaniam
    acto et musici inde periculum. Authore Roberto South Art. Bac. ex Aede Christi. Oxonii, Typis
    Leon. Lichfield Academiae Typographi, Impensis Tho. Robinson. Anno 1655. \\ 
  λ & \textit{Überarbeitete, zweite Fassung des Gedichts zwischen 1655 und 1667.} \\ 
  W & Musica incantans sive poema exprimens musicae vires juvenem in insaniam adigentis et
    musici inde periculum. Authore Roberto South Art. Bac. ex Aede Christi. Oxonii, Typis W.\,H.,
    Impensis G. West. Anno Dom. 1667. \\ 
\end{longtblr}

\end{document}
