仍然是一个用 `tcolorbox` 的方案，做了一定的抽象。凑合吧 如果完全使用表格来做，需要 patch 很底层的实现。 ```tex \documentclass{ctexart} \usepackage[table]{xcolor} % load colortbl package \usepackage{tcolorbox} \tcbuselibrary{hooks} % allow use of option "before upper pre" \makeatletter \tcbset{ rounded tabular/.style={ tabulars={*{5}{c|}}, % preamble of "{tabular*}" env colback=magenta!30, % background color arc=0.8em, % radius of arc, magic number width=0.8\linewidth, % total width set all rules=0.6pt % width of frame rule and tabular vrule }, set all rules/.style={ boxrule=#1, before upper pre={% \setlength{\arrayrulewidth}{#1}% } } } \makeatother \newtcolorbox{rtabular}[1][]{ rounded tabular/.append style={#1}, rounded tabular } \begin{document} \tcbset{ rounded tabular/.append style={ tabulars={ *{2}{>{\centering}p{4em}|} *{3}{>{\centering}p{3em}|} }, width=0.9\linewidth, set all rules=0.6pt } } \begin{rtabular} 检测基因 & NFE2L2 & NQO1 & SOD2 & CAT \end{rtabular} \begin{rtabular} 检\qquad 因 & NFE & NO & SO & C \end{rtabular} \end{document} ```
