折叠 longtblr 中的垂直空间

折叠 longtblr 中的垂直空间

我有一个tabularray longtblr由多组行组成的表格,这些行之间由额外的垂直空间隔开。当一个组位于表格页面的末尾时,它会在该组和底部之间产生难看的空间\hline

当页面底部出现多余的垂直空间时,有没有办法将其折叠起来?

本示例代码:

\documentclass{article}

\usepackage{tabularray}

\begin{document}
\begin{longtblr}{colspec=lX,width=\textwidth,rowsep=0pt}
  \hline
  Head \\
  \hline
  \multicolumn{2}{l}{Group 1} \\*
  & 1.1 \\[2ex]
  \multicolumn{2}{l}{Group 2} \\*
  & 2.1 \\[2ex]
  \multicolumn{2}{l}{Group 3} \\*
  & 3.1 \\[2ex]
  \multicolumn{2}{l}{Group 4} \\*
  & 4.1 \\[2ex]
  \multicolumn{2}{l}{Group 5} \\*
  & 5.1 \\[2ex]
  \multicolumn{2}{l}{Group 6} \\*
  & 6.1 \\[2ex]
  \multicolumn{2}{l}{Group 7} \\*
  & 7.1 \\[2ex]
  \multicolumn{2}{l}{Group 8} \\*
  & 8.1 \\[2ex]
  \multicolumn{2}{l}{Group 9} \\*
  & 9.1 \\[2ex]
  \multicolumn{2}{l}{Group 10} \\*
  & 10.1 \\[2ex]
  \multicolumn{2}{l}{Group 11} \\*
  & 1.1 \\[2ex]            
  \multicolumn{2}{l}{Group 12} \\*
  & 2.1 \\[2ex]            
  \multicolumn{2}{l}{Group 13} \\*
  & 3.1 \\[2ex]            
  \multicolumn{2}{l}{Group 14} \\*
  & 4.1 \\[2ex]            
  \multicolumn{2}{l}{Group 15} \\*
  & 5.1 \\[2ex]            
  \multicolumn{2}{l}{Group 16} \\*
  & 6.1 \\[2ex]            
  \multicolumn{2}{l}{Group 17} \\*
  & 7.1 \\[2ex]            
  \multicolumn{2}{l}{Group 18} \\*
  & 8.1 \\[2ex]            
  \multicolumn{2}{l}{Group 19} \\*
  & 9.1 \\
  \hline

答案1

(1)您可以用白色水平线替换行下方的垂直空间;分页符处的水平线将被删除。

(2)您可以\multicolumn\SetCell;替换,\multicolumn命令将在 2022 版本中删除。
