如何调整表格的列间距？

Question

大家好，我注意到 LaTeX 中表格每列之间的间距不太好（至少对我来说）。有什么方法可以解决这个问题吗？运行以下代码后，获取附加的图像形式。请帮助解决该问题...我必须以这种格式维护表格。我正在为 IOS Press 杂志使用 Latex 模板。所以我正在使用 IOS 类。

\documentclass[aic]{iosart2x}
\usepackage{dcolumn}
\newcolumntype{d}[1]{D{.}{.}{#1}}
\begin{document}
\begin{table*}[htb]
\caption{Table caption} \label{tab:title}
\begin{tabular}{ll d{1} d{1}}
\hline
&\textbf{ABCD}&\multicolumn{1}{l}{$COV(\#/\%)$}&
\multicolumn{1}{l}{$DSC(\#/\%)$}\\
\hline
FLOPs&SDD-16                  &10,937M/91.3 &121.1M/8.7 \\
& DD                          &1,352M/92.0  & 117M/8.0\\ [6pt]
Storage&SDD-16                &7.15M/5.58   & 121.1M/94.42\\
& DD                          &2.3M/3.75    & 59M/96.25\\
\hline
\end{tabular}
\end{table*} 
\end{document}

Answer 1

尝试

\documentclass[aic]{article}
\usepackage{dcolumn}
\newcolumntype{d}[1]{D{M}{M}{#1}} % <--- changed anchor, now is M

\begin{document}
\begin{table*}[htb]
\caption{Table caption} \label{tab:title}
\begin{tabular}{ll d{4} d{5}}
\hline
&\textbf{ABCD}&\multicolumn{1}{l}{$COV(\#/\%)$}&
\multicolumn{1}{l}{$DSC(\#/\%)$}\\
\hline
FLOPs&SDD-16                  &10,937M/91.3 &121.1M/8.7 \\
& DD                          &1,352M/92.0  & 117M/8.0\\ [6pt]
Storage&SDD-16                &7.15M/5.58   & 121.1M/94.42\\
