我正在尝试创建一个大致如下图所示的图表：
除了我希望它有圆角。似乎最明显的方法是使用 tikz，所以我尝试了以下方法：
\documentclass{standalone}
\usepackage{tikz}
\usepackage{braket}
\usetikzlibrary{matrix,fit}
\begin{document}
\newcommand{\objboxthreer}[7]{
\begin{tikzpicture}
\matrix (m) [nodes={inner sep=2pt},matrix of nodes, nodes in empty cells,ampersand replacement=\&, row sep=0pt, column sep=0pt]
{
{#1} \& \& {#2} \& {#4} \& {#6} \& \\
\& \& {#3} \& {#5} \& {#7} \& \\
};
\node [
draw,
rounded corners=.5em,
inner sep=0pt,
outer sep=0pt,
minimum size=0pt,
fit=(m-1-2.north east)
(m-1-2.south east)
(m-1-3.north east)
(m-1-3.south east)
(m-1-4.north east)
(m-1-4.south east)
(m-1-5.north east)
(m-1-5.south east)
(m-1-6.north west)
(m-1-6.south west)] {};
%\draw [rounded corners=.5em] (m-1-2.south east) rectangle (m-3-6.north west);
\draw (m-1-3.north east) -- (m-1-3.south east);
\draw (m-1-4.north east) -- (m-1-4.south east);
\end{tikzpicture}
}
\objboxthreer{d}{$p_s$}{$Y_d$}{$p_d$}{$Y_d'$}{$\{p\}$}{$\Set{ x \in X | x > 5}$}
\end{document}
这产生了不太令人满意的结果：
垂直线未到达封闭框的顶部或底部。
挑战在于，此表格中所有单元格的内容大小都非常动态。每个元素的高度和宽度都可能发生很大变化（复杂的公式等），因此我无法简单地指定每行和每列的高度和宽度。我如何才能模拟第一个表格但带有圆角？
这里有一个具有更高元素的附加测试用例：\documentclass{standalone} \usepackage{tikz} \usepackage{braket} \usetikzlibrary{matrix,fit}
\begin{document}
\newcommand{\objboxthreer}[7]{
\begin{tikzpicture}
\matrix (m) [nodes={inner sep=2pt},matrix of nodes, nodes in empty cells,ampersand replacement=\&, row sep=0pt, column sep=0pt]
{
{#1} \& \& {#2} \& {#4} \& {#6} \& \\
\& \& {#3} \& {#5} \& {#7} \& \\
};
\node [
draw,
rounded corners=.5em,
inner sep=0pt,
outer sep=0pt,
minimum size=0pt,
fit=(m-1-2.north east)
(m-1-2.south east)
(m-1-3.north east)
(m-1-3.south east)
(m-1-4.north east)
(m-1-4.south east)
(m-1-5.north east)
(m-1-5.south east)
(m-1-6.north west)
(m-1-6.south west)] {};
%\draw [rounded corners=.5em] (m-1-2.south east) rectangle (m-3-6.north west);
\draw (m-1-3.north east) -- (m-1-3.south east);
\draw (m-1-4.north east) -- (m-1-4.south east);
\end{tikzpicture}
}
\objboxthreer{d}{$p_s$}{$Y_d$}{$\left\{\frac{p}{q}\right\}$}{$Y_d'$}{$\{p\}$}{$\Set{ x \in X | x > 5}$}
\end{document}
其输出有类似的问题，但无法通过使用以下方法解决\strut：
答案1
虽然添加\strut可以解决基本文本的问题，但是如果您想允许更多可变高度，则\vphantom需要添加基于最高条目高度的：

代码：
\documentclass{standalone}
\usepackage{tikz}
\usepackage{braket}
\usetikzlibrary{matrix,fit}
\begin{document}
\newcommand{\objboxthreer}[7]{%
\newcommand{\MyStrut}{\vphantom{#1#2#3#4#5#6#7}}%
\begin{tikzpicture}
\matrix (m) [nodes={inner sep=2pt},matrix of nodes, nodes in empty cells,ampersand replacement=\&, row sep=0pt, column sep=0pt]
{
{#1\MyStrut} \& \& {#2\MyStrut} \& {#4\MyStrut} \& {#6\MyStrut} \& \\
\& \& {#3\MyStrut} \& {#5\MyStrut} \& {#7\MyStrut} \& \\
};
\node [
draw,
rounded corners=.5em,
inner sep=0pt,
outer sep=0pt,
minimum size=0pt,
fit=(m-1-2.north east)
(m-1-2.south east)
(m-1-3.north east)
(m-1-3.south east)
(m-1-4.north east)
(m-1-4.south east)
(m-1-5.north east)
(m-1-5.south east)
(m-1-6.north west)
(m-1-6.south west)] {};
%\draw [rounded corners=.5em] (m-1-2.south east) rectangle (m-3-6.north west);
\draw (m-1-3.north east) -- (m-1-3.south east);
\draw (m-1-4.north east) -- (m-1-4.south east);
\end{tikzpicture}%
}
\objboxthreer{d}{$p_s$}{$Y_d$}{$\left\{ \frac{p}{q} \right\}$}{$Y_d'$}{$\{p\}$}{$\Set{ x \in X | x > 5}$}
\end{document}
答案2
用最少的工具解决，没有matrix但有shape multiple parts
\documentclass{article}
\usepackage{tikz}\usepackage{braket}
\usetikzlibrary{shapes.multipart}
\begin{document}
\setlength{\fboxsep}{0pt}
\begin{tikzpicture}[%
table shape/.style={rectangle split,
rectangle split part align=base,
rectangle split horizontal,
rectangle split parts=3,
rounded corners},
p3/.style={text width=18ex,align=center}]
\node [table shape,draw] (main)
{$p_s$
\nodepart{two}$p_d$
\nodepart[p3]{three}$\{p\}$};
\node [table shape] at ([yshift=-2em]main.center)
{$Y_d$
\nodepart{two}$Y'_d$
\nodepart[p3]{three}$\Set{ x \in X | x > 5}$};
\node at ([xshift=-3ex]main.text west) {d};
\end{tikzpicture}
\end{document}
