使用 xltabular 创建带有长表的两列

Question

我有一本两栏的书，里面有跨多页的长表格。它们工作得很好，当然，长表格不适用于两栏文档。因此，我不得不求助于在长表格前后引入\onecolumn和\twocolumn来使其工作，就像这个技巧在表格后引入分页符一样。

因此，我一直在试验这个xltabular软件包，试图找到解决分页符问题的方法，但似乎没有效果。

我是否注定要在双栏书中的长表格后添加分页符，不管它们是用longtable还是创建的xltablular？（是的，我的一些长表格有脚注）。

只有使用包才能实现双列模式的表格supertabular：

\documentclass[twocolumn]{book}
\usepackage[english]{babel}
\usepackage{showframe}
\usepackage{array,supertabular}
\usepackage{booktabs} % Nicer spacing in columns
\usepackage{blindtext}
\newsavebox\WBox

\begin{document}

\sbox\WBox{Left column}% The widest entry in the l column   
\topcaption{The \texttt{xltabular} environment with \texttt{longtable} propertyand left aligned by 
    setting the optional argument.}
\begin{supertabular}{
  @{} 
  p{\wd\WBox}
  p{\dimexpr\columnwidth-\wd\WBox-2\tabcolsep\relax}
  @{}}\toprule
    Left column & At first a line with some nonsense text to show how long this line is.The caption has 
    the same width as the text.\\
    left column & \blindtext\\
    left column & \blindtext\\
    left column & \blindtext\\
    left column & \blindtext\\
    left column & \blindtext\\
\bottomrule
\end{supertabular}

\blindtext

\end{document}
