如何在表格中画垂直线？

Question 1

更新后续问题之后：解决方案无法编译。（见下文）

可以绘制垂直线，而不会与booktabs使用nicematrix包冲突。

第二个表格的单元格对齐效果更好。使用X列来调整其相对宽度和居中。

唯一需要添加的包是nicematrix https://ctan.org/pkg/nicematrix?lang=en

\documentclass{article}
\usepackage{booktabs}

\usepackage{nicematrix} % added <<<<<<<<<<<<<<<<<<<<<<<<<<<<<

\begin{document}


\noindent\begin{NiceTabular}{lp{1.5in}|lp{1.5in}}
    \toprule
    Parameter & Description & Parameter & Description\\
    \midrule
    $\mu$ & Influx rate of the population & $\epsilon$ & Progression rate from $I_1$ to $I_2$ \\
    $\beta_1$ & Transmission rate of the fast latent compartment & $p_1$ & Progression rate from $I_2$ to $J$ \\
    $\beta_2$ & Transmission rate of the symptomatic compartment & $p_2$ & Progression rate from $J$ to $A$ \\
    $\beta_3$ & Transmission rate of the AIDS compartment & $\xi_1$ & Treatment rate from $J$ to $I_1$ \\
    $p$ & Fraction of S infected by $I_2$ who enter $I_1$ & $\xi_2$ & Treatment rate from $J$ to $I_2$ \\
    $q$ & Fraction of S infected by $J$ who enter $I_1$ & $\nu$ & Natural death rate \\
    $r$ & Fraction of S infected by $A$ who enter $I_1$ & $\alpha$ & Disease related death rate \\

要试用最新版本nicematrix 没有安装它：

下载nicematrix.zip 自nicematrix.zip
提取目录nicematrix。
在该目录中打开命令窗口并执行 pdflatex nicematrix.ins。
该文件nicematrix.sty将被生成。
将该文件复制到你的工作目录并编译你的表

更新检查软件包的版本

尝试使用此代码来检查软件包的版本

输出将产生两个非常相似的表，第一个使用tabularray（来自 Zarko 的答案），第二个使用nicematrix

如果失败，请运行以下代码

    \listfiles % list the files loaded <<<<<<<<<<<<<<
    \documentclass{article}     
    \usepackage{geometry}
    \usepackage{tabularray} 
    \UseTblrLibrary{booktabs}
    \usepackage{nicematrix}
            
    \begin{document}
        
        Only to list the files loaded

    \end{document}

重要的\documentclass{article}在命令之前查看\listfiles

现在看看文件的末尾.log。

您应该会看到已加载的所有文件的列表，类似于

如果您安装的是以前的版本，我建议您更新它们。

我正在使用 MiKTeX 发行版，其中此任务是使用 MiKTeX 控制台完成的。
