Question

我在以下代码中遇到了意外行为：

\documentclass[tikz,border=3pt]{standalone}

\usetikzlibrary{shapes.multipart,positioning}

\begin{document}

\begin{tikzpicture}
        \node[draw,rectangle split,
        rectangle split parts=3,
        rectangle split part fill={red!20,blue!20,yellow!80!red!20},
        rectangle split ignore empty parts](top){%
            Box 1
            \nodepart{two}Box 2
            \nodepart{three}\parbox{2in}{Box 3 which really can contain a lot of text just to see what is going on here}};
    \node[below=1em of top,
        draw,rectangle split,
        rectangle split parts=3,
        rectangle split part fill={red!20,blue!20,yellow!80!red!20},
        rectangle split ignore empty parts]{%
            Box 1
            \nodepart{three}\parbox{2in}{Box 3 which really can contain a lot of text just to see what is going on here}};
\end{tikzpicture}

\end{document}

nodepart{three}当 缺失时，无法正确填充nodepart{two}，因此被忽略。我简化了代码—— 是\parbox必需的，因为 中的文本有一些复杂的要求nodepart{three}。

有解决方法吗？

更新

我感兴趣的是为什么它不起作用，而从表面上看，它应该起作用。蓝色表示必需的位；黄色表示应该做什么。有时没有必要的位，因此不应显示单元格——但会有解释性文字，由黄色背景表示。TikZ 似乎能够自动执行此操作，但有一个我指出的问题。如果这还不够清楚，我深表歉意。

我出于各种原因需要 TikZ，并且并没有真正寻找替代解决方案。我尝试了各种表格，但结果并不令人满意。

解决方法

这不是我问题的答案，但让我回去工作......

\documentclass[tikz,border=3pt]{standalone}

\usetikzlibrary{shapes.multipart,positioning,backgrounds}

\begin{document}

\begin{tikzpicture}
    \node[draw,rectangle split,
        rectangle split parts=3,
        rectangle split part fill={red!20,blue!20,none},
        rectangle split ignore empty parts] (X) {%
            Box 1
            \nodepart{three}\parbox{2in}{Box 3 which really can contain a lot of text just to see what is going on here}};
    \begin{scope}[on background layer]
        \draw[fill=yellow!80!red!20] (X.north west) rectangle (X.south east);
    \end{scope}
\end{tikzpicture}

\end{document}

使用tblrfromtabularray会容易得多：

\documentclass{article}
\usepackage{xcolor}
\usepackage{tabularray}

\begin{document}
\begin{tblr}{colspec={p{7cm}}, 
            hlines, vlines, 
            row{1-Y}={halign=c},
            row{1}={bg=red!20}, 
            row{2-Y}={bg=blue!20},
            row{Z}={bg=yellow!80!red!20}}
Box 1 \\
Box 2 \\
Box 3 which really can contain a lot of text just to see what is going on here
\end{tblr}
\medskip

\begin{tblr}{colspec={p{7cm}}, 
            hlines, vlines, 
            row{1-Y}={halign=c},
            row{1}={bg=red!20}, 
            row{2-Y}={bg=blue!20},
            row{Z}={bg=yellow!80!red!20}}
Box 1 \\
Box 3 which really can contain a lot of text just to see what is going on here
\end{tblr}
\medskip


\begin{tblr}{colspec={p{7cm}}, 
            hlines, vlines, 
            row{1-Y}={halign=c},
            row{1}={bg=red!20}, 
            row{2-Y}={bg=blue!20},
            row{Z}={bg=yellow!80!red!20}}
Box 1 \\
Box 2 \\
Box 2 \\
Box 2 \\
Box 3 which really can contain a lot of text just to see what is going on here
\end{tblr}
\end{document}
