删除 Latex 表中列表之间的空格

我想删除图片上红线所示的空格。我尝试了很多方法，但似乎都行不通。提前谢谢。

只需添加选项noitemsep以逐项列出列表，如果仍然不满足于额外的间距，则添加负垂直间距\vspace{-\baselineskip}——表格的示例部分显示在下面的屏幕截图中

  • 请始终随表格提供完整、可编译的小文档。此类文档在前言中提供有关文档页面布局、使用的相关包等信息，这些信息会影响表格设计。
  • 对于内容只有一行的列，我宁愿使用l和'r'列类型
  • 为了在单元格中获得更多垂直空间，我建议使用包makegapedcells中的宏makecell
  • 我将为表格中的列表\setlist定义通用样式itemize
