如果文档的行距为双倍或半倍，而要求表格的行距为单倍，那么如何保留表格标题和注释的文档间距？
apa6在使用类的 MWE（由 pandoc 模板生成）中，man类选项将文档设置为 12pt 并设置双倍行距。通过使用setspace、etoolbox和caption包，我能够通过在 处硬编码拉伸因子来实现所需的结果（忽略表格标题上方和表格注释下方的间距）1.655，我在 中找到了setspace.sty这种字体大小和行距组合。
但是，我正在寻找一个通用的解决方案，能够将表格标题和注释的行距恢复为\baselinestretch文档开头的值。（即，无论正文行距是多少，都会应用于表格标题和注释，而不管表格行的行距是多少）。
