在表格环境中扩展边框

Question

对于下面的背对背茎叶图，您将如何修改代码以使突出显示的部分显示出来？出于某种奇怪的原因，当我编译 latex 时，它丢失了。

谢谢

\documentclass[]{article}
\usepackage[margin=0.5in]{geometry}
\usepackage{pgfplots}
\usepgfplotslibrary{fillbetween}
\usepgfplotslibrary{statistics}
\newenvironment{tightcenter}{
\setlength\topsep{0pt}
\setlength\parskip{0pt}
\begin{center}}{\end{center}}
\begin{document}
\begin{table}[htbp]
\begin{tabular}{lllll|c|lllllll}
\multicolumn{5}{r}{\textbf{Town 1}} & \textbf{Stem} & \multicolumn{6
}{l}{\textbf{Town 2}}\\[0.024cm]\hline
  & 7 & 3 & 2 & 1 & 2 & 5 & 6 & 6 & 9 &   &\\[0.124cm]
  & 8 & 4 & 3 & 0 & 3 & 1 & 1 & 2 & 6 & 8 & 9\\[0.124cm]
8 & 6 & 5 & 3 & 2 & 4 & 1 & 4 & 6 & 7 &   & \\[0.124cm]
\end{tabular}
\end{table}
\end{document}

Answer 1

使用 来{r|}代替，{r}您可以添加垂直线的缺失部分。

\documentclass[]{article}
\usepackage[margin=0.5in]{geometry}
\begin{document}
\begin{table}[htbp]
\begin{tabular}{lllll|c|lllllll}
\multicolumn{5}{r|}{\textbf{Town 1}} & \textbf{Stem} & \multicolumn{6
}{l}{\textbf{Town 2}}\\[0.024cm]\hline
  & 7 & 3 & 2 & 1 & 2 & 5 & 6 & 6 & 9 &   &\\[0.124cm]
  & 8 & 4 & 3 & 0 & 3 & 1 & 1 & 2 & 6 & 8 & 9\\[0.124cm]
8 & 6 & 5 & 3 & 2 & 4 & 1 & 4 & 6 & 7 &   & \\[0.124cm]
\end{tabular}
\end{table}
\end{document}

Answer 2

如果您使用{NiceTabular}而nicematrix不是{tabular}，您将直接获得预期的输出。

\documentclass{article}
\usepackage[margin=0.5in]{geometry}
\usepackage{nicematrix}

\begin{document}

\begin{table}[htbp]

\begin{NiceTabular}{lllll|c|llllll}
\multicolumn{5}{r}{\textbf{Town 1}} & \textbf{Stem} & \multicolumn{6
}{l}{\textbf{Town 2}}\\[0.024cm]\hline
  & 7 & 3 & 2 & 1 & 2 & 5 & 6 & 6 & 9 &   &\\[0.124cm]
  & 8 & 4 & 3 & 0 & 3 & 1 & 1 & 2 & 6 & 8 & 9\\[0.124cm]
8 & 6 & 5 & 3 & 2 & 4 & 1 & 4 & 6 & 7 &   & \\[0.124cm]
\end{NiceTabular}

\end{table}

\end{document}
