使用 booktabs 的 toprule 将第一行表格与文本垂直对齐

Question

顶部对齐tabular将其第一行的基线与周围文本的基线对齐。但是，当使用booktabs'时\toprule，该规则被视为第一行，因此与此基线对齐。

\documentclass{article}

\usepackage{booktabs}

\begin{document}

this is some text
\begin{tabular}[t]{l l}
  o & p \\
  q & r \\
\end{tabular}
this is some text

this is some text
\begin{tabular}[t]{l l}\toprule
  o & p \\
  q & r \\\bottomrule
\end{tabular}
this is some text

\end{document}

我怎样才能将的第一个“真实”行tabular与\toprule周围的线对齐？

Answer 1

您可以{NiceTabular}使用nicematrix。

\documentclass{article}
\usepackage{nicematrix}
\usepackage{booktabs}

\begin{document}

this is some text
\begin{tabular}[t]{l l}
  o & p \\
  q & r \\
\end{tabular}
this is some text

this is some text
\begin{NiceTabular}[t]{l l}\toprule
  o & p \\
  q & r \\\bottomrule
\end{NiceTabular}
this is some text

\end{document}

您需要多次编译（因为nicematrix在后台使用 PGF/Tikz 节点）。

Answer 2

booktabs一种选择是使用 来伪造规则tcolorbox。结果语法不如使用 好nicematrix，如F. Pantigny 的回答，但只需编译一次即可。（当然可以编写包装器环境。）

\documentclass{article}

\usepackage{booktabs}
\usepackage{tcolorbox}

\newtcolorbox{fakebooktabsrules}{
  hbox,
  nobeforeafter,
  tcbox raise base,
  arc=0pt,
  boxrule=\heavyrulewidth,
  leftrule=0pt,
  rightrule=0pt,
  boxsep=0pt,
  top=\belowrulesep,
  bottom=\aboverulesep,
  left=0pt,
  right=0pt,
  colback=white,
  colframe=.,
}

\begin{document}

this is some text
\begin{tabular}[t]{l l}
  o & p \\
  q & r \\
\end{tabular}
this is some text

this is some text
\begin{tabular}[t]{l l}\toprule
  o & p \\
  q & r \\\bottomrule
\end{tabular}
this is some text

this is some text
\begin{fakebooktabsrules}
  \begin{tabular}[t]{l l}
    o & p \\
    q & r \\
  \end{tabular}
\end{fakebooktabsrules}
this is some text

\end{document}
