tcolorbox 内的 Tabularx：列大小和对齐问题

Question

考虑以下代码，源自这答案并产生如本文底部所示的输出。

\documentclass[a4paper, 10pt]{article}
\usepackage[margin=2cm]{geometry}
\usepackage[listings,skins,theorems,breakable,most]{tcolorbox}
\usepackage{lipsum}
\usepackage{fancyhdr}
\usepackage{tabularx}
\usepackage{xcolor}
\usepackage{multicol}

\NewDocumentCommand{\tcbtab}{O{}m+m}{%
  \begin{tcolorbox}[%
    enhanced,
    arc = 0pt,
    outer arc = 0pt,
    titlerule = 0pt,
    boxsep = 0pt,
    left = 0pt,
    right = 0pt,
    top=0pt,
    colframe = black,
    box align=center,
    halign=center,
    valign=center,
    attach boxed title to top={xshift=0mm,yshift=0mm},
    boxed title style={
    enhanced,
    colback = black,
    arc=0pt,
    outer arc=0pt,
    },
    listing only,
    title = {\centering\makebox[\linewidth][c]{#2}},#1]
    #3%
    \end{tcolorbox}%
}

\begin{document}
\lipsum[1]
\tcbtab{Title}{
\begin{tabularx}{\linewidth}{|p{0.5\linewidth}|p{0.5\linewidth}|}
First column & Second column 
\end{tabularx}
}
\lipsum[1]
\begin{multicols}{2}
\lipsum[1]
\tcbtab{Title}{
\begin{tabularx}{\linewidth}{|p{0.5\linewidth}|p{0.5\linewidth}|}
First column & Second column 
\end{tabularx}
}
\lipsum[1-2]
\end{multicols}
\end{document}

现在我已经tcolorboxes对齐并居中了，我想在其中放置表格。但是，当前方法没有给出预期的结果，因为列太宽了。

我希望能够指定一个tabularx位置，我可以轻松指定p{0.2\something}*5或类似的内容，如果我想要 5 个多行列，或者p{0.5\something}*2，如果我想要 2 个多行列，或者p{0.2\something}|p{0.2\something}|c如果我想要 2 个多行列和 1 个填充所有剩余空间的居中列。

语法可能有点不同，但我希望能够轻松设计盒装表格，而无需花费数小时手动对齐每列以使其看起来美观。并且结果应该与和兼容\multicolumn。\multirow如何实现这一点？（以及如何删除数组内部前后的垂直空间the tcolorbox？）

使用tabularx模式tcolorbox（并删除那里的方框标题）。
