tcolorbox：修复 tcbitemize 的行高

Question

我需要一个像这样的 tcbitemize 结构总高6cm。

我该如何设置，使第一行的高度仅为约 2 厘米？（第二行：“休息”。）

\documentclass{article}
\usepackage[showframe=true]{geometry}

\usepackage[most]{tcolorbox}
\tcbset{
SymbolStyle/.style={boxrule=4pt,colframe=blue}, 
NoGaps/.style={boxsep=0pt, 
left=0pt, right=0pt, top=0pt, bottom=0pt,}, 
}

\begin{document}
\begin{tcolorbox}[
colframe=red,  boxrule=2pt, 
NoGaps, 
]
\begin{tcbitemize}[
% Problem here ======================
%row 1/.style={height=2cm,},  % no effect
raster height=6cm, % raster rows=2,
raster equal height=rows,
% ===============================
sharp corners, boxrule=1pt,
NoGaps, boxsep=3pt,
raster columns=100,
raster column skip=0pt,
raster row skip=0pt,
colback=white
]
\tcbitem[raster multicolumn=25, SymbolStyle, 
%height=4cm  % no effect
]  X
\tcbitem[raster multicolumn=15] Y
\tcbitem[raster multicolumn=60] Z
\tcbitem[raster multicolumn=60] a \\ 1 \\ 2\\ 3 \\ 4\\ 5 \\ 6 \\ 7 \\8
\tcbitem[raster multicolumn=40] b
\end{tcbitemize}
\end{tcolorbox}
\end{document}

Answer 1

指定第一行高度的选项名为raster row 1，而不是row 1。选项tcb/raster row m记录在记录tcolorbox，第 15.4 节。

\documentclass{article}
\usepackage[showframe=true]{geometry}

\usepackage[most]{tcolorbox}
\tcbset{
  SymbolStyle/.style={boxrule=4pt, colframe=blue}, 
  NoGaps/.style={boxsep=0pt, left=0pt, right=0pt, top=0pt, bottom=0pt},
  draw height/.style={
    enhanced,
    finish={
      \draw[blue,very thick,<->] 
        (frame.south) -- node[right,pos=.75] {#1} +(0,#1); 
    }
  }
}

\begin{document}
\begin{tcolorbox}[
  colframe=red, boxrule=2pt,
  NoGaps, 
  height=6cm,
  draw height=6cm
]
  \begin{tcbitemize}[
    enhanced,
    raster row 1/.style={height=2cm},
    % 4pt = doubled the width of outer boxrule
    raster row 2/.style={height=4cm-4pt},
    raster equal height=rows,
    sharp corners, boxrule=1pt,
    NoGaps, boxsep=3pt,
    raster columns=100,
    raster column skip=0pt,
    raster row skip=0pt,
    raster before skip=0pt,
    raster after skip=0pt,
    colback=white,
  ]
    \tcbitem[raster multicolumn=25, SymbolStyle]  X
    \tcbitem[raster multicolumn=15] Y
    \tcbitem[raster multicolumn=60, draw height=2cm] Z
    \tcbitem[raster multicolumn=60] a \\ 1 \\ 2\\ 3 \\ 4\\ 5 \\ 6 \\ 7 \\8
    \tcbitem[raster multicolumn=40] b
  \end{tcbitemize}
\end{tcolorbox}

\end{document}

该选项draw height仅用于绘制测量箭头，您可以在实际使用中安全地将其删除。

Answer 2

这种不规则结构可以通过 轻松获得tcbposter（也可以从tcolorbox这样的包中获得tcbraster）。虽然海报应该具有规则的结构，但可以更改所有框的高度、宽度和位置。甚至可以定义框，其高度由其他框之间的空间决定。

以下代码显示了如何使用 获得所需的结构tcbposter。在这种情况下，使用一列两行的海报作为主要结构。span选项可以定义每个框的宽度，而column=1、column*=1和xshift用于固定框的水平位置。第一行框定义为，below=top因为这样它们的高度由其内容或 tcolorboxheight选项固定。第二行框定义为between = ... and bottom填充所有剩余的垂直空间。

\documentclass{article}

\usepackage{geometry}

\usepackage[most]{tcolorbox}
\tcbset{
    SymbolStyle/.style={boxrule=4pt,colframe=blue},
    NoGaps/.style={boxsep=0pt, left=0pt, right=0pt, top=0pt, bottom=0pt},
}

\begin{document}
\begin{tcbposter}[
    poster = {%showframe,
     columns=1, rows = 2, spacing=0pt, height=6cm},
    boxes = {sharp corners, colframe=red, boxrule=1pt, NoGaps, boxsep=3pt, colback=white, enhanced}
]
\posterbox[SymbolStyle, height=2cm]{name=X, column=1, below=top, span=.25}{X}
\posterbox[height=2cm]{name=Y, row=1, span=.15, xshift=.25\linewidth}{Y}
\posterbox[height=2cm]{name=Z, column*=1, span=.60, below=top}{Z}
\posterbox{name=a, between=X and bottom, span=.6, column=1}{a\\ 1\\ 2\\ 3\\ 4\\ 5\\ 6\\ 7\\ 8}
\posterbox{name=b, between=Z and bottom, span=.6, column*=1}{b}
\end{tcbposter}
