這個問題與此類似:加粗時表中的小數與 dcolumn 不對齊
我希望帶有 dcolumn 的表格中的某些數字為斜體並與其他數字對齊。我嘗試了類似粗體數字的建議:
\newcolumntype{I}[3]{>{\textit\DC@{#1}{#2}{#3}}c<{\DC@end}}
然而,這不起作用。
例子:
\documentclass[12pt]{article}
\usepackage{dcolumn}
\newcolumntype{.}{D{.}{.}{-1}}
\makeatletter
\newcolumntype{B}[3]{>{\boldmath\DC@{#1}{#2}{#3}}c<{\DC@end}}
\makeatother
\begin{document}
\begin{tabular}{..}
\hline
1.5 & 0.19 \\
\multicolumn{1}{B{.}{.}{-1}}{2.75} & 4.2 \\
3.4 & \textit{8.0} \\
\hline
\end{tabular}
\end{document}
答案1
最簡單的方法就是指定字型兩次
\documentclass[12pt]{article}
\usepackage{dcolumn}
\newcolumntype{.}{D{.}{.}{-1}}
\makeatletter
\newcolumntype{B}[3]{>{\boldmath\DC@{#1}{#2}{#3}}c<{\DC@end}}
\makeatother
\begin{document}
\begin{tabular}{..}
\hline
1.5 & 0.19 \\
\multicolumn{1}{B{.}{.}{-1}}{2.75} & 4.2 \\
3.4 & \mathit{8}.\mathit{0} \\
\hline
\end{tabular}
\end{document}

您可以定義一個新的數學版本來獲取斜體數字,但我將首先提出一個基於siunitx
(部分來自https://tex.stackexchange.com/a/334323/4427)
\documentclass[12pt]{article}
\usepackage{siunitx,booktabs,etoolbox}
\begin{document}
\begin{table}
\centering
%% local redefinitions
\renewrobustcmd{\bfseries}{\fontseries{b}\selectfont}
\renewrobustcmd{\boldmath}{}
\begin{tabular}{
S[table-format=1.2,detect-weight,mode=text]
S[table-format=1.2,detect-weight,mode=text]
}
\toprule
1.5 & 0.19 \\
\bfseries 2.75 & 4.2 \\
3.4 & \itshape 8.0 \\
\bottomrule
\end{tabular}
\end{table}
\end{document}
替代方案,具有dcolumn
:
\documentclass[12pt]{article}
\usepackage{dcolumn}
\DeclareMathVersion{italic}
\SetSymbolFont{operators}{italic}{OT1}{\familydefault}{m}{it}
\newcolumntype{.}{D{.}{.}{-1}}
\makeatletter
\newcolumntype{B}[3]{>{\boldmath\DC@{#1}{#2}{#3}}c<{\DC@end}}
\newcolumntype{I}[3]{>{\mathversion{italic}\DC@{#1}{#2}{#3}}c<{\DC@end}}
\makeatother
\begin{document}
\begin{tabular}{..}
\hline
1.5 & 0.19 \\
\multicolumn{1}{B{.}{.}{-1}}{2.75} & 4.2 \\
3.4 & \multicolumn{1}{I{.}{.}{-1}}{8.0} \\
\hline
\end{tabular}
\end{document}
答案3
與 David 的想法相同,但為了方便起見,將其封裝到巨集中:
\documentclass[12pt]{article}
\usepackage{dcolumn}
\newcolumntype{.}{D{.}{.}{-1}}
\makeatletter
\newcolumntype{B}[3]{>{\boldmath\DC@{#1}{#2}{#3}}c<{\DC@end}}
\makeatother
% call \mathit separately for integer and decimal parts
\newcommand{\itnum}[2]{\mathit{#1}.{\mathit{#2}}}
\begin{document}
\begin{tabular}{..}
\hline
1.5 & 0.19 \\
\multicolumn{1}{B{.}{.}{-1}}{2.75} & 4.2 \\
3.4 & \itnum{8}{0} \\
\hline
\end{tabular}
