使用 siunitx 语法对表格中的小数点进行对齐时，数学语法不起作用

我遇到了以下问题：数学语法不适用于表格中第二行的标签 h=1、h=3、h=6。我该如何修复？

这是我的代码。谢谢

这是表格的一部分。我tabularx在最后一列使用了自动换行符，threeparttablex用于表格注释的格式，添加了一些sisetup选项并删除了不必要的\multicolumn命令以及空行。现在由您来调整表格的其余部分。

在此处输入图片描述

\newcommand*{\oneS}{\SuperScriptSameStyle{*}} 
\newcommand*{\twoS}{\SuperScriptSameStyle{**}} 
\newcommand*{\threeS}{\SuperScriptSameStyle{*{*}*}}
