- 我们如何在 MWE 中第一个表的第二列后插入一条垂直线？
- 我们如何才能使第二个表格看起来像第一个表格（线条粗细相同并删除外边框线）但在第二列后插入一条垂直线？
编辑：
对于2)，我做了：
\documentclass{article}
\usepackage{tabularray}
\UseTblrLibrary{booktabs, siunitx}
\begin{document}
\begin{table}[!htb]
\small
\noindent\begin{tblr}{colspec = { Q[c,$] X[l] |
Q[c,$] X[l] },
row{1} = {mode=text},
row{2-Y} = {belowsep+=2pt},
cells = {font=\fontsize{10}{11}}
}
\toprule
Parameter & Description & Parameter & Description\\
\midrule
x & Influx rate of the population
& x & Progression rate of asymptomatic to symptomatic compartment \\
x & Natural death rate
& x & Self-recovery rate of asymptomatic individuals \\
x & Transmission rate of the asymptomatic compartment
& x & Self-recovery rate of symptomatic individuals \\
x & Transmission rate of the symptomatic compartment
& x & Treatment rate of symptomatic individuals \\
x & Vaccination proportion of newborns
& x & Immunity loss rate \\
x & Vaccination rate of susceptibles
& x & Disease induced death rate \\
\bottomrule
\end{tblr}
\caption{x}
\end{table}
\end{document}
但是顶部规则和底部规则是否与 MWE 中的第一个表格相同？对我来说，它看起来比 MWE 中的第一个表格“更薄”，但我可能错了？
答案1
（我只会回答您的第一个问题，您应该将其他问题移至新帖子）
您可以使用vline{3}={solid}在第二列后添加垂直线。然而，这会使您原本漂亮的表格看起来不那么专业。
相反，我建议分割第二条水平线来表示划分：
\documentclass{article}
\usepackage{tabularray}
\UseTblrLibrary{booktabs, siunitx}
\begin{document}
\begin{table}[!htb]
\noindent\begin{tblr}{
colspec = {*{4}{Q[c,$]}},
vline{3}={solid},
row{1} = {mode=text},
row{2-Y} = {belowsep+=2pt}
}
\toprule
Parameter & Sensitivity index & Parameter & Sensitivity index\\
\midrule
x & +1.000
& x & -0.328 \\
x & -0.788
& x & -0.344 \\
x & +0.231
& x & -0.518 \\
x & +0.124
& x & -0.023 \\
x & -5.785
& \xi & +0.364 \\
x & -0.731
& x & -0.004 \\
\bottomrule
\end{tblr}
\caption{x}
\end{table}
\begin{table}[!htb]
\noindent\begin{tblr}{
colspec = {*{4}{Q[c,$]}},
row{1} = {mode=text},
row{2-Y} = {belowsep+=2pt}
}
\toprule
Parameter & Sensitivity index & Parameter & Sensitivity index\\
\cmidrule[r]{1-2} \cmidrule[l]{3-4}
x & +1.000
& x & -0.328 \\
x & -0.788
& x & -0.344 \\
x & +0.231
& x & -0.518 \\
x & +0.124
& x & -0.023 \\
x & -5.785
& \xi & +0.364 \\
x & -0.731
& x & -0.004 \\
\bottomrule
\end{tblr}
\caption{x}
\end{table}

答案2
使用siunitx库和分组行，仅需第一个表：
documentclass{article}
\usepackage{tabularray}
\UseTblrLibrary{booktabs, siunitx}
\begin{document}
\begin{table}[!htb]
\centering
\begin{tblr}{vline{3} = solid, % <---
colspec = {*{2}{Q[c,mode=math]Q[c, si={table-format=-1.3}]}},
row{1} = {guard, mode=text},
row{2-Z} = {rowsep=0pt},
row{even[4-Z]} = {abovesep=3pt},
}
\toprule
Parameter & Sensitivity index & Parameter & Sensitivity index\\
\midrule
x & 1.000 & x & -0.328 \\
x & -0.788 & x & -0.344 \\
x & 0.231 & x & -0.518 \\
x & 0.124 & x & -0.023 \\
x & -5.785 & \xi & 0.364 \\
x & -0.731 & x & -0.004 \\
