我有一张长表格，跨越几页，我需要这张表格的最后一条水平线每个页面加粗。但是，我只让最后一页的水平线加粗。有没有什么办法可以解决这个问题？（可能类似于头部，让头部在每一页上都被粗线包围，效果很好？）
以下是一个例子：
\documentclass[12pt]{article}
\usepackage{xltabular}
\textheight7cm
\newcolumntype{I}{!{\vrule width 0.8pt}}
\begin{document}
\begin{xltabular}{\linewidth} {I X | X | X I}
\noalign{\hrule height 0.8pt}
\textbf{Header column 1} & \textbf{Header column 2} & \textbf{Header column 3} \\
\noalign{\hrule height 0.8pt}
\endhead
\hline Text column 1 & Text column 2 & Text column 3 \\
\hline
\hline Text column 1 & Text column 2 & Text column 3 \\
\hline
\hline Text column 1 & Text column 2 & Text column 3 \\
\hline
\hline Text column 1 & Text column 2 & Text column 3 \\
\hline
\hline Text column 1 & Text column 2 & Text column 3 \\
\hline
\hline Text column 1 & Text column 2 & Text column 3 \\
\hline
\hline Text column 1 & Text column 2 & Text column 3 \\
\hline
\hline Text column 1 & Text column 2 & Text column 3 \\
\hline
\hline Text column 1 & Text column 2 & Text column 3 \\
\hline
\hline Text column 1 & Text column 2 & Text column 3 \\
\hline
\hline Text column 1 & Text column 2 & Text column 3 \\
\hline
\hline Text column 1 & Text column 2 & Text column 3 \\
\hline
\hline Text column 1 & Text column 2 & Text column 3 \\
\hline
\hline Text column 1 & Text column 2 & Text column 3 \\
\hline
\hline Text column 1 & Text column 2 & Text column 3 \\
\hline
\hline Text column 1 & Text column 2 & Text column 3 \\
\hline
\hline Text column 1 & Text column 2 & Text column 3 \\
\hline
\hline Text column 1 & Text column 2 & Text column 3 \\
\hline
\hline Text column 1 & Text column 2 & Text column 3 \\
\hline
\hline Text column 1 & Text column 2 & Text column 3 \\
\hline
\hline Text column 1 & Text column 2 & Text column 3 \\
\hline
\hline Text column 1 & Text column 2 & Text column 3 \\
\hline
\hline Text column 1 & Text column 2 & Text column 3 \\
\hline
\hline Text column 1 & Text column 2 & Text column 3 \\
\hline
\hline Text column 1 & Text column 2 & Text column 3 \\
\hline
\hline Text column 1 & Text column 2 & Text column 3 \\
\hline
\hline Text column 1 & Text column 2 & Text column 3 \\
\hline
\hline Text column 1 & Text column 2 & Text column 3 \\
\hline
\hline Text column 1 & Text column 2 & Text column 3 \\
\hline
\hline Text column 1 & Text column 2 & Text column 3 \\
\noalign{\hrule height 0.8pt}
\end{xltabular}
\end{document}

类似于\endhead和\endfirsthead的还有\endfoot和`\endlastfoot。
为了达到预期的效果，你可能需要使用
\noalign{\hrule height 0.8pt}
\endhead
\noalign{\hrule height 0.8pt}
\endfoot
