我有这个问题：我想在表格底部加框。目前它看起来像这样：
\begin{table}[ht]
\centering
\begin{tabular}{|c|c|c|c|c|c|} \hline
$\sim$ Light intensity & Total & Upwards & Downwards & True positive & False positive\\ \hline
228 & 64 & 32 & 32 & 16 & 0 \\
217 & 112 & 56 & 56 & 22 & 0 \\
181 & 48 & 24 & 24 & 5 & 0 \\
164 & 80 & 40 & 40 & 1 & 0 \\
150 & 64 & 32 & 32 & 1 & 0 \\\hline
Total & 368 & 184 & 184 & 45 & 0 \\\specialrule{.2em}{.1em}{.1em}
Found [\%] & 12.23\% & True positive & 100\% & False positive & 0\% \\ \specialrule{.2em}{.1em}{.1em}
\end{tabular}
\caption{Testing of method 2BB with a performance of 100\%}
\label{tab:method6}
\end{table}
我希望它看起来像这样：
希望你们能帮助我！ 问候 Emil

以下 MWE 包含改编自我之前的回答。我还加入了另外两种使用之前提到过 booktabs包裹。
\documentclass{article}
\usepackage{geometry}
\usepackage{booktabs}
\usepackage{array}
\newlength{\defaultarrayrulewidth}
\newcommand{\Cline}[2]{%
\noalign{\global\setlength{\defaultarrayrulewidth}{\arrayrulewidth}}%
\noalign{\global\setlength{\arrayrulewidth}{#1}}\cline{#2}%
\noalign{\global\setlength{\arrayrulewidth}{\defaultarrayrulewidth}}}

使用来自包的厚规则的解决方案makecell（另一种可能性是使用该boldline包）：
\documentclass{article}
\usepackage{array, makecell, booktabs}
\setlength{\extrarowheight}{2pt}
\begin{document}
\begin{table}[ht]
\centering
\begin{tabular}{|*{6}{c|}}

228 & 64 & 32 & 32 & 16 & 0 \\
217 & 112 & 56 & 56 & 22 & 0 \\
181 & 48 & 24 & 24 & 5 & 0 \\
164 & 80 & 40 & 40 & 1 & 0 \\
