我有下面这个表格。如何让白色间距均匀，并将 0 放在中间？
\begin{table}\centering
\scriptsize
\begin{tabularx}{\linewidth}{@{}l *{1}{>{\centering\arraybackslash}X} c *{5}{>{\centering\arraybackslash}X} c *{4}{>{\centering\arraybackslash}X} }
\toprule
& \multicolumn{1}{c}{Train (Complete)} & \multicolumn{5}{c}{Test (Complete)} & & \multicolumn{4}{c}{Test (Truncated)} \\
\cmidrule(l{2pt}r{2pt}){2-2} \cmidrule(l{2pt}r{2pt}){3-7} \cmidrule(l{2pt}r{2pt}){9-12}
& 0s & 0s & 1s & 2s & 3s & 4s & & 1s & 2s & 3s & 4s \\
\midrule
Single Image & 65k,175k & 10k,24k & - & - & - & - & & 1.8k, 23k & - & 46.3 & 46.0 \\
Single Keypoint & 59k,121k & 9k,18k & - & - & - & - & & 1.7k, 18k & - & - & - \\
\midrule
Multiple Image & 60k,150k & 9k,20k & - & - & - & - & & 1.5k, 19k & - & - & - \\
Multiple Keypoints & 54k,98k & 8k,15k & - & - & - & - & & 1.4k, 14k & - & - & - \\
\bottomrule
\end{tabularx}

\end{table}
答案1
您的某些 X 列太窄。我将它们转换为c，然后删除了multicolumn两个不必要的位置。此外，我添加了一个额外的空列作为新的第四列来平衡空白。另一种可能性是删除两个空列并将其替换为固定宽度的空间，方法是使用!{\hspace{<wd>}}：
\documentclass{article}
\usepackage{tabularx, booktabs,
\usepackage[left=3cm, right=3cm]{geometry}
\begin{document}
\begin{table}\centering
\scriptsize
\begin{tabularx}{\linewidth}{@{}l *{3}{c} *{4}{>{\centering\arraybackslash}X} cc *{3}{>{\centering\arraybackslash}X}@{}}
\toprule
& {Train (Complete)} && \multicolumn{5}{@{}c@{}}{Test (Complete)} && \multicolumn{4}{@{}c@{}}{Test (Truncated)} \\
\cmidrule(lr){2-2} \cmidrule(lr){4-8} \cmidrule(l){10-13}
& {0s} && 0s & 1s & 2s & 3s & 4s && 1s & 2s & 3s & 4s \\ \midrule
Single Image & 65k,175k && 10k,24k & - & - & - & - && 1.8k,23k & - & 46.3 & 46.0 \\
Single Keypoint & 59k,121k && 9k,18k & - & - & - & - && 1.7k,18k & - & - & - \\ \midrule
Multiple Image & 60k,150k && 9k,20k & - & - & - & - && 1.5k,19k & - & - & - \\
Multiple Keypoints & 54k,98k && 8k,15k & - & - & - & - & & 1.4k,14k & - & - & - \\ \bottomrule
\end{tabularx}

我会以不同的方式分布列和它们的宽度：
\documentclass{article}
\usepackage[margin=3cm]{geometry}
\usepackage{booktabs,tabularx}
\begin{document}
\begin{table}\centering
\scriptsize
\setlength\cmidrulekern{0.25em}
\begin{tabularx}{\linewidth}{@{}
l
>{\raggedleft\hsize=1.2\hsize}X@{,}>{\raggedright\hsize=1.2\hsize}X
r@{,}l
*{4}{>{\centering\arraybackslash\hsize=0.9\hsize}X}
r@{,}l
*{3}{>{\centering\arraybackslash}X}
@{}}
\toprule
& \multicolumn{2}{c}{Train (Complete)}
& \multicolumn{6}{c}{Test (Complete)}
& \multicolumn{5}{c}{Test (Truncated)} \\
\cmidrule(lr){2-3}
\cmidrule(lr){4-9}
\cmidrule(l){10-14}
& \multicolumn{2}{@{}c}{0s}
& \multicolumn{2}{c}{0s}
& 1s & 2s & 3s & 4s & \multicolumn{2}{c}{1s}
& 2s & 3s & 4s \\ \midrule
Single Image
& 65k & 175k & 10k & 24k & - & - & - & - & 1.8k & 23k & - & 46.3 & 46.0\\
Single Keypoint
& 59k & 121k & 9k & 18k & - & - & - & - & 1.7k & 18k & - & - & - \\ \midrule
Multiple Image
& 60k& 150k & 9k & 20k & - & - & - & - & 1.5k & 19k & - & - & - \\
Multiple Keypoints
& 54k &98k & 8k & 15k & - & - & - & - & 1.4k & 14k & - & - & - \\
\bottomrule
\end{tabularx}
\caption{}
\label{tab:traintestsplit}
\end{table}
\end{document}
