Answer 1

这里的关键是将显示的标题更改为Biologically treated effluents (mg/l)\hfill\mbox{}，并添加\hfill。

 \caption[Biologically treated effluents (mg/l)]{%
  Biologically treated effluents (mg/l)\hfill\mbox{}}

Answer 2

答案对我有用。我借此机会将\hlines 和\clines 替换为规则，booktabs因为您加载了它，并在 中的表格底部键入了引用\footnotesize。我认为如果居中，第一行中的两个\multicolumns 看起来会更好。最后：我使用了tabularx而不是tabular*：
