将 hfill 延伸至单元格的边界

Question

我用来\hrulefill\hfill创建水平线。问题是这些线没有接触单元格的边框。我怎样才能让它们接触单元格的垂直边框线？

ASCII 艺术示例：

现在我明白了

| Class 1 | Class 2 |
|  ---------------  |

我想得到这个

| Class 1 | Class 2 |
|-------------------|

优先使用tabular替代环境的解决方案。tabularx

以下是 MWE：

\documentclass{article}
\usepackage[english]{babel}

\usepackage{array}

\begin{document}

\begin{tabular}{|c|>{\centering}p{2em}|>{\centering}p{2em}|>{\centering}p{2em}|>{\centering}p{2em}|}
\hline 
 & \multicolumn{2}{c|}{Class 1} & \multicolumn{2}{c|}{Class 2}\tabularnewline
\hline 
A & \multicolumn{4}{c|}{\hrulefill\hfill}\tabularnewline
\hline 
B &  & \hrulefill\hfill & \hrulefill\hfill & \tabularnewline
\hline 
\end{tabular}

\end{document}

Answer 1

您需要\tabcolsep通过以下几种方式之一来解释：

\documentclass{article}
\usepackage[english]{babel}

\usepackage{array}

\begin{document}

\begin{tabular}{|c|>{\centering}p{2em}|>{\centering}p{2em}|>{\centering}p{2em}|>{\centering}p{2em}|}
\hline 
 & \multicolumn{2}{c|}{Class 1} & \multicolumn{2}{c|}{Class 2}\tabularnewline
\hline 
A & \multicolumn{4}{c|}{\hrulefill\hfill}\tabularnewline
\hline 
B &  & \hrulefill\hfill & \hrulefill\hfill & \tabularnewline
\hline 
\end{tabular}

\bigskip

\begin{tabular}{|c|>{\centering}p{2em}|>{\centering}p{2em}|>{\centering}p{2em}|>{\centering}p{2em}|}
\hline 
 & \multicolumn{2}{c|}{Class 1} & \multicolumn{2}{c|}{Class 2}\tabularnewline
\hline 
A & \multicolumn{4}{@{}c@{}|}{\hrulefill}\tabularnewline
\hline 
B &  & \multicolumn{1}{@{}c@{}|}{\hrulefill}& 
\multicolumn{1}{@{}c@{}|}{\hrulefill} & \tabularnewline
\hline
1&2&3&4\tabularnewline
\hline 
\end{tabular}

\bigskip



{\setlength\tabcolsep{0pt}
\begin{tabular}{|c|>{\centering}p{2em}|>{\centering}p{2em}|>{\centering}p{2em}|>{\centering}p{2em}|}
\hline 
 & \multicolumn{2}{c|}{Class 1} & \multicolumn{2}{c|}{Class 2}\tabularnewline
\hline 
A & \multicolumn{4}{c|}{\hrulefill}\tabularnewline
\hline 
B &  & \hrulefill & \hrulefill & \tabularnewline
\hline 
\end{tabular}}

\bigskip

\begin{tabular}{|c|>{\centering}p{2em}|>{\centering}p{2em}|>{\centering}p{2em}|>{\centering}p{2em}|}
\hline 
 & \multicolumn{2}{c|}{Class 1} & \multicolumn{2}{c|}{Class 2}\tabularnewline
\hline 
A & \multicolumn{4}{c|}{\mbox{}\kern-\tabcolsep\hrulefill\kern-\tabcolsep}\tabularnewline
\hline 
B &  &\mbox{}\kern-\tabcolsep\hrulefill\kern-\tabcolsep &
 \mbox{}\kern-\tabcolsep\hrulefill\kern-\tabcolsep & \tabularnewline
\hline 
\end{tabular}
