正确对齐长表中的最后一列

我需要一些帮助来将最后一列中的数字与\cdotAND 小数对齐。同时将数字与标题居中。谢谢。

这是我的代码：

\pgfplotsset{compat=newest}
\usepackage{longtable}
\usepackage{booktabs}

\usepackage[a4paper,top=1in,bottom=1in,right=1in,left=1in]{geometry} 

\usepackage{filecontents}

答案1

column type={c}与 不兼容dec sep align。实际上dec sep align意味着两列r@{}l。这就是标题用 完成的原因\multicolumn{2}。

你能做的最好的事情就是

columns/eucl-min-dist/.style={sci, sci zerofill, dec sep align},

但相对于标题居中是不可能的。
