调整 tcolorbox 中的可破坏长表

Question

我需要一个tcolorbox有longtable内部的，但我无法调整正确的利润。

实际上，我想要一个圆形的标题和一个带有可破坏表格的框架，可以放置在页面的任何地方。

注意：我已经尝试了0pt找到的每个选项但似乎还不够......

例子：

代码：

\documentclass[a4paper,11pt]{report}

\usepackage[table]{xcolor} %colr
\usepackage[raster,skins]{tcolorbox} %textbox
\usepackage{setspace}
\usepackage{longtable}

\usepackage[left=2.5cm, right=2cm, bottom=1cm]{geometry}
\tcbuselibrary{listings,breakable}

\begin{document}%\layout

\vspace*{550px}


\setlength{\LTpre}{0pt}
\setlength{\LTpost}{0pt}
\setlength{\LTleft}{0pt}
\setlength{\LTright}{0pt}

\tcbset{
    breakable,  enhanced,   
    left*=0pt,right*=0pt,
    top=0pt,bottom=0pt,
    toptitle=0mm, bottomtitle=0mm,
    boxsep=0pt,left=0pt,right=0pt,
    boxrule=2pt, % NO EFFECT
}

\begin{tcolorbox}\textsl{•}[title=\strut\textsc{This is a colorbox}]
\begin{longtable}[]{l|p{0.4\textwidth}|p{0.4\textwidth}|l}

    \multicolumn{4}{c}{\cellcolor{black}\color{white} \textbf{\textsc{This is the table header}} } \\ \hline
    1 & text description & second text & date \\ \hline
    2 & text description &  second text & date \\ \hline
    3 & text description &  second text & date \\ \hline
    4 & text description &  second text & date \\ \hline
    5 & text description &  second text & date \\ \hline
    6 & text description &  second text & date \\ \hline
    7 & text description &  second text & date \\ \hline
    8 & text description &  second text & date \\ \hline
    9 & text description &  second text & date \\ \hline
    11 & text description &  second text & date \\ \hline
    12 & text description &  second text & date \\ \hline
    13 & text description &  second text & date \\ \hline
    14 & text description &  second text & date \\ \hline
    15 & text description &  second text & date \\ \hline 
\end{longtable}
\end{tcolorbox}

\end{document}

这段代码有什么问题？还有其他替代方案吗？

Answer 1

您的表格不够宽，因为所有列的宽度加在一起不等于\textwidth。

为了简化正确宽度的计算，您可以使用包X提供的列类型xltabular，它将延伸到剩余空间。如果您希望使用longtable，则应使用xltabular结合了longtable和tabularx包的包。

\documentclass[a4paper,11pt]{report}

\usepackage[table]{xcolor} %colr
\usepackage[raster,skins]{tcolorbox} %textbox
\usepackage{setspace}
\usepackage{xltabular}

\usepackage[left=2.5cm, right=2cm, bottom=1cm]{geometry}
\tcbuselibrary{listings,breakable}

\begin{document}%\layout

\vspace*{550px}

\setlength{\LTpre}{0pt}
\setlength{\LTpost}{0pt}
\setlength{\LTleft}{0pt}
\setlength{\LTright}{0pt}

\tcbset{
    breakable, enhanced,   
    left*=0pt, right*=0pt,
    top=0pt, bottom=0pt,
    toptitle=0mm, bottomtitle=0mm,
    boxsep=0pt, left=0pt, right=0pt,
    boxrule=2pt, % NO EFFECT
}

\begin{tcolorbox}[title=\strut\textsc{This is a colorbox}]
\begin{xltabular}{\textwidth}{l|p{0.3\textwidth}|p{0.3\textwidth}|X}
    \multicolumn{4}{c}{\cellcolor{black}\color{white} \textbf{\textsc{This is the table header}} } \\ \hline
    1 & text description & second text & date \\ \hline
    2 & text description &  second text & date \\ \hline
    3 & text description &  second text & date \\ \hline
    4 & text description &  second text & date \\ \hline
    5 & text description &  second text & date \\ \hline
    6 & text description &  second text & date \\ \hline
    7 & text description &  second text & date \\ \hline
    8 & text description &  second text & date \\ \hline
    9 & text description &  second text & date \\ \hline
    11 & text description &  second text & date \\ \hline
    12 & text description &  second text & date \\ \hline
    13 & text description &  second text & date \\ \hline
    14 & text description &  second text & date \\ \hline
    15 & text description &  second text & date \\ \hline 
\end{xltabular}
\end{tcolorbox}

\end{document}
