tcbraster 中的最大可能高度

Question

在以下情况下，当外部左框高于外部右框时，我希望内部框（外部右框的光栅内）具有尽可能大的高度。

\documentclass[11pt]{article}

\usepackage{tcolorbox}
\tcbuselibrary{skins}
\tcbuselibrary{raster}

\begin{document}

\tcbset{%
    outer left/.style={frame hidden, boxrule=0pt, boxsep=5pt, colback=yellow, halign=center, valign=center},
    outer right/.style={frame hidden, boxrule=0pt, boxsep=2pt, colback=orange, halign=center, valign=center},
    inner right/.style={boxsep=3pt, halign=center, valign=center}
}
\begin{tcbraster}[raster columns=2, raster equal height=rows, raster valign=center]
    \begin{tcolorbox}[outer left]
            w\\
            x\\
            y\\
            z
    \end{tcolorbox}
    %
    \begin{tcolorbox}[outer right]
        \begin{tcbraster}[raster columns=3]
            \begin{tcolorbox}[inner right]
                d
            \end{tcolorbox}
            %
            \begin{tcolorbox}[inner right]
                e
            \end{tcolorbox}
            %
            \begin{tcolorbox}[inner right]
                f
            \end{tcolorbox}
        \end{tcbraster}
    \end{tcolorbox}
\end{tcbraster}

\end{document}

我想出了一个 hacky 解决方案（远非完美），经过两次连续编译后似乎有效。

\documentclass[11pt]{article}

\usepackage{tcolorbox}
\tcbuselibrary{skins}
\tcbuselibrary{raster}

\begin{document}

\tcbset{%
    outer left/.style={frame hidden, boxrule=0pt, boxsep=5pt, colback=yellow, halign=center, valign=center},
    outer right/.style={frame hidden, boxrule=0pt, boxsep=2pt, colback=orange, halign=center, valign=center},
    inner right/.style={boxsep=3pt, halign=center, valign=center, ht}
}

\makeatletter
\begin{tcbraster}[raster columns=2, raster equal height=rows, raster valign=center]
    \begin{tcolorbox}[outer left]
            w\\
            x\\
            y\\
            z
    \end{tcolorbox}
    %
    \begin{tcolorbox}[outer right,
            code={%
                    \edef\tcb@ehgid{\kvtcb@raster@ehgid @\number\c@tcbrasterrow}%
                    \ifcsundef{tcb@ehg@height@\tcb@ehgid}%
                        {\tcbset{ht/.style={}}}%
                        {%
                                \tcbheightfromgroup\myht{\tcb@ehgid}%
                                \tcbdimto\myresult{\kvtcb@top@rule@stand+\kvtcb@bottom@rule@stand+\kvtcb@boxsep*2+\kvtcb@top+\kvtcb@bottom}%
                                \iftcb@hasTitle%
                                    \tcbdimto\myresult{\tcbtextheight+\ht\tcb@titlebox+\dp\tcb@titlebox+\kvtcb@title@rule+\kvtcb@boxsep*2+\kvtcb@toptitle+\kvtcb@bottomtitle}%
                                \fi%
                                \tcbdimto\myresult{\myht-\myresult}%
                                \tcbset{ht/.style={height=\myresult}}%
                        }%
            }
]
        \begin{tcbraster}[raster columns=3]
            \begin{tcolorbox}[inner right]
                d
            \end{tcolorbox}
            %
            \begin{tcolorbox}[inner right]
                e
            \end{tcolorbox}
            %
            \begin{tcolorbox}[inner right]
                f
            \end{tcolorbox}
        \end{tcbraster}
    \end{tcolorbox}
\end{tcbraster}
\makeatother

\end{document}

但是这个解决方案要求我删除辅助文件，如果代码有任何改变（框内容或设置等等boxsep），就需要重新编译两次。

有谁有更好的解决方案吗？谢谢！

Answer 1

我想我已经找到了解决我的问题的方法，它基于密钥的使用space to。

如果是包含在外面的右框中的tcolorbox，我们可以使用该add to natural height键。

另一方面，如果它是一个光栅，height当外部右框没有其自然高度（\myspace>0pt）时，我们将使用该键。

    inner right/.style={boxsep=3pt, halign=center, valign=center, ht}
}
