我使用 RStudio 中的“stargazer”包创建了这些描述性统计表，我想在这个表下写一个注释，但我做不到。我唯一能做的就是写一个注释，但这没有道理。

答案1
\resizebox我建议使用而不是 ，tabularx并结合较小的字体大小和缩小的\tabcolsep。在下面的例子中，我还用包中的线条替换了水平线booktabs，并在相邻行之间添加了一个小的垂直空白作为眼睛的引导。对于表格注释，我使用了\multicolumn：

由于“N”列中的所有条目基本相同，您可以完全删除该列并将此信息添加到表格的标题中吗？结果可能如下所示：

我怀疑你正在寻找这样的东西：
使用threeparttable、cellspace和siunitx包：
