带有表格的Tcolorbox规则宽度

带有表格的Tcolorbox规则宽度

显然，该命令对于内部具有 tabularx 的boxrule增强功能不起作用。tcolorbox

我如何指定 tabularx 周围框架的宽度？

这是 MWE：

\documentclass{article}
\usepackage[skins]{tcolorbox}
\usepackage{array,tabularx}
\usepackage{colortbl}
\begin{document}

% \usepackage{array,tabularx}
% \usepackage{colortbl} - or - \usepackage[table]{xcolor}
\tcbset{enhanced,fonttitle=\bfseries\large,fontupper=\normalsize\sffamily,
    colback=yellow!10!white,colframe=red!50!black,colbacktitle=red!30!white,
    coltitle=black,center title,
    boxrule=10pt, % NO EFFECT
}
\begin{tcolorbox}[tabularx*={\arrayrulewidth0.5mm}{X|X|X},title=My table]
    One
    & Two
    & Three \\\hline\hline
    1000.00 & 2000.00 & 3000.00\\\hline
    2000.00 & 3000.00 & 4000.00
\end{tcolorbox}

% EDIT : with a multicolumn as 1st cell this does not compile anymore
\begin{tcolorbox}[boxrule=2pt,tabularx*={\arrayrulewidth2pt}{YY|YY|YY},
    title=My table
    ]
    \multicolumn{2}{c|}{title}
    &   \multicolumn{2}{c|}{title}
    &   \multicolumn{2}{c}{title} \\\hline
    2 & d & 3 & e & 4 & f \\\hline
    title & \multicolumn{3}{|l|}{h} & \multicolumn{1}{c|}{title} & j \\
\end{tcolorbox}

\end{document}

编辑 ：对于 MWE 中的第一个表，第一个答案是可以的，但我使用 amulticolumn作为第一个单元格，这会带来Misplaces \omit错误。MWE 已使用有问题的表进行了修改。

答案1

样式的定义tabularx已将设置为boxrule。0.5mm您可以通过从源复制样式并删除此部分来覆盖该设置：

\documentclass{article}
\usepackage[skins]{tcolorbox}
\usepackage{array,tabularx}
\usepackage{colortbl}
\begin{document}

% \usepackage{array,tabularx}
% \usepackage{colortbl} - or - \usepackage[table]{xcolor}
\tcbset{enhanced,fonttitle=\bfseries\large,fontupper=\normalsize\sffamily,
    colback=yellow!10!white,colframe=red!50!black,colbacktitle=red!30!white,
    coltitle=black,center title,
    boxrule=10pt, % NO EFFECT
}
\makeatletter
\tcbset{tabularx*/.style 2 args={%
    boxsep=\z@,top=\z@,bottom=\z@,leftupper=\z@,rightupper=\z@,
    toptitle=1mm,bottomtitle=1mm,% boxrule setting here removed
    before upper={\arrayrulecolor{tcbcol@frame}\def\arraystretch{1.1}#1%
      \tcb@hack@currenvir\tabularx{\linewidth}{#2}},
    after upper=\endtabularx\arrayrulecolor{black}}}
\makeatother
\begin{tcolorbox}[tabularx*={\arrayrulewidth0.5mm}{X|X|X},title=My table]
    One
    & Two
    & Three \\\hline\hline
    1000.00 & 2000.00 & 3000.00\\\hline
    2000.00 & 3000.00 & 4000.00
\end{tcolorbox}
\end{document}

结果：

编辑：在较新版本中，该tcolorbox定义略有更改。在这种情况下，新定义应如下：

\tcbset{tabularx*/.style 2 args={%
    boxsep=\z@,top=\z@,bottom=\z@,leftupper=\z@,rightupper=\z@,
    toptitle=1mm,bottomtitle=1mm,
    before upper*={%
      \let\tcb@CT@arc@save\CT@arc@%
      \arrayrulecolor{tcbcolframe}\def\arraystretch{1.1}#1%
      \tcb@hack@currenvir\tabularx{\linewidth}{#2}},
    after upper*={\endtabularx\global\let\CT@arc@\tcb@CT@arc@save}%
  }
}

答案2

如果需要改变boxrule选项指定的值tabularx*，那么tabularx*/.append style={boxrule=<dimen>}更简单，其中.append style是预定义的处理程序之一pgfkeys。

完整示例：

\documentclass{article}
\usepackage[skins]{tcolorbox}
\usepackage{array,tabularx}
\usepackage{colortbl}

\tcbset{
    enhanced,
    fonttitle=\bfseries\large,
    fontupper=\normalsize\sffamily,
    colback=yellow!10!white,
    colframe=red!50!black,
    colbacktitle=red!30!white,
    coltitle=black,
    center title,
    % change boxrule set by "tabularx*", by default it's 0.5mm
    tabularx*/.append style={boxrule=10pt}
}

\begin{document}
\begin{tcolorbox}[tabularx*={\arrayrulewidth0.5mm}{X|X|X}, title=My table]
    One
    & Two
    & Three \\\hline\hline
    1000.00 & 2000.00 & 3000.00\\\hline
    2000.00 & 3000.00 & 4000.00
\end{tcolorbox}
\end{document}

更新

只是为了好玩。这里定义了一个在包内部使用的新pgfkeys处理程序。.patch code={<search>}{<replace>}\xpatchcmdxpatch

\documentclass{article}
\usepackage{tcolorbox}
\usepackage{xpatch}

\usepackage{array,tabularx}

  \pgfkeysifdefined{\pgfkeyscurrentpath/.@args}%
  {% Yes, so add to body and reuse args
    \pgfkeyspatchvalue{\pgfkeyscurrentpath/.@body}{#1}{#2}%
    % Redefine code

\makeatother
