如何在长表中的标题周围添加彩色框架？

我想tcolorbox在长桌的标题周围放置一个彩色填充框（例如带有包装的框），我将其放入其中\endlastfoot。我使用了以下问题的答案：带框的标题和图片，带彩色标题对于我的其他图形/表格，但无法使其在长表环境中工作。我已使用这个问题的答案给长桌涂上颜色尝试为多行标题着色，但无法使其看起来美观且有框架。

答案1

感谢 Axel，我找到了一个可能的解决方案。由于我对 Latex 还比较陌生，而且不太习惯使用宏，请告诉我我犯的任何错误，或者直接编辑我的答案：

彩色填充框架LTcaptionbox的代码：

\usepackage[many]{tcolorbox}

    \makeatletter
    \newtcolorbox{LTcaptionbox}[7][]{enhanced, colframe=gray, colback=gray!30, arc=0pt, outer arc=0pt, boxrule=0.7pt, before={}, #1}
    \DeclareCaptionOption{stuffforbox}{\def\caption@stuffforbox{#1}}

    \DeclareCaptionBox{myLTbox}{%
      \begin{LTcaptionbox}[code={\pgfkeysalsofrom{\caption@stuffforbox}}]
        #2%
      \end{LTcaptionbox}%
    }
    \makeatother
    \captionsetup[longtable]{stuffforbox={}, box={myLTbox}, slc=off}

还有我编辑的表格（我添加了'tabu'包来填充整个页面，并调整'\bottomrule'和LTCaptionbox到相同的宽度）

\documentclass[a4paper, 12pt]{report}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[english,ngerman]{babel}
\usepackage[margin=2cm]{geometry}
\setlength{\parindent}{5mm}

\makeatletter
\newtcolorbox{LTcaptionbox}[7][]{enhanced, colframe=gray, colback=gray!30, arc=0pt, outer arc=0pt, boxrule=0.7pt, before={}, #1}
\DeclareCaptionOption{stuffforbox}{\def\caption@stuffforbox{#1}}

\DeclareCaptionBox{myLTbox}{%
  \begin{LTcaptionbox}[code={\pgfkeysalsofrom{\caption@stuffforbox}}]
    #2%
  \end{LTcaptionbox}%
}
\makeatother
\captionsetup[longtable]{stuffforbox={}, box={myLTbox}, slc=off}

PS：我无法将“\columncolor”与“Longtabu”的 X 列一起使用。有人知道这个问题的可能解决方案吗？
如果您想保留“Longtable”环境，您只需使用：

\newlength\q
\setlength\q{\dimexpr 0.166\textwidth -2\tabcolsep\relax}

和

\begin{longtable}{p{\q}|p{\q} >{\columncolor[gray]{.95}\centering\arraybackslash}p{\q} >{\centering\arraybackslash}p{\q} >{\columncolor[gray]{.95}\centering\arraybackslash}p{\q} >{\centering\arraybackslash}p{\q}}
