集中詞彙表的組標題

Question

我一直glossaries-extra在論文中生成符號列表，但我一直在格式化方面苦苦掙扎。更具體地說，問題是我的章節標題居中，但術語表組標題不是居中。

我已經看過畫廊了自訂群組區塊還有不同的格式style，但我還沒有找到解決方案。理想情況下，清單應類似於style=long（參見下圖），但包含居中的群組標題。

有沒有簡單的方法可以將詞彙表的組標題置中？

微量元素：

\documentclass[parskip,12pt,oneside,a4paper]{scrbook}
\usepackage[record,symbols,nomain,stylemods={tree},shortcuts=other]{glossaries-extra}

\renewcommand*{\raggedchapter}{\centering}% Make chapters centred
\addtokomafont{disposition}{\rmfamily}% Roman fonts for Ch

\glsxtrsetgrouptitle{bte}{Neutron transport}
\glsxtrsetgrouptitle{angdisc}{Angular discretisations}

\begin{document}

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\newentry{r}{
  name={\ensuremath{\mathbf{r}}},
  description={Position},
  group={bte},
  type={symbols}
}
\newentry{S2}{
  name={\ensuremath{\mathit{S_2}}},
  description={Angular domain: the unit sphere},
  group={bte},
  type={symbols}
}

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\newentry{SN}{
  name={\ensuremath{S_N}},
  description={Discrete Ordinates discretisation of \gls{S2}},
  group={angdisc},
  type={symbols}
}
\newentry{PN}{
  name={\ensuremath{P_N}},
  description={Spherical Harmonics discretisation of \gls{S2}},
  group={angdisc},
  type={symbols}
}

% \printunsrtglossary[type=symbols,style=long,title={List of Symbols}]
\printunsrtglossary[type=symbols,style=indexgroup,title={List of Symbols}]
\clearpage

\end{document}

Answer 1

要回答這個問題，您可以簡單地使用以下命令更新格式

\renewcommand\glstreegroupheaderfmt[1]{\begin{center}\textbf{#1}\end{center}\vspace{-\parskip}}

並切換到alttreegroup風格。因此您也必須使用

\glsfindwidesttoplevelname

在 的調用之前\printunsrtglossary。最後它應該看起來像這樣：

Answer 2

在測試了一些替代方案（包括 @Venez 發布的答案）後，我認為解決這個問題的最簡單的解決方案是定義一個基於long.該long樣式實際上是 a，longtable這意味著簡單的列操作可以產生所要求的樣式，即居中的群組標題和術語表條目放置在頁面的中心。

解決方案：

\documentclass[parskip,12pt,oneside,a4paper]{scrbook}
\usepackage[record,symbols,nomain,stylemods={tree},shortcuts=other]{glossaries-extra}% list of symbols

\renewcommand*{\raggedchapter}{\centering}% Make chapters centred
\addtokomafont{disposition}{\rmfamily}% Roman fonts for Ch

\glsxtrsetgrouptitle{bte}{Neutron transport}
\glsxtrsetgrouptitle{angdisc}{Angular discretisations}

% Define a custom long style for groups; style=long uses longtables
\newglossarystyle{longgroup}{%
    \setglossarystyle{long}%
  \renewcommand*{\glsgroupheading}[1]{%
    &%  Add empty column in longtable 
    \multicolumn{1}{c}{% Change the alignment just for the group title to centre
          \glsxtrgetgrouptitle{##1}{\glsxtrgrptitle}%
          % \glstreePreHeader{##1}{\glsxtrgrptitle}%
      \glstreegroupheaderfmt{\glsxtrgrptitle}%
    }%
    \cr% newline in table
    %\glsgroupskip% Uncomment for additional spacing below group title
    }%
}%
