\begin{document}
\begin{table}
\centering
\begin{tabular}{cSS}

答案2
不交换列和行:
通过使用tabularray
表格并在第一列启用两行文本:
\documentclass{article}
\usepackage{tabularray}
\UseTblrLibrary{siunitx}
\begin{document}
\begin{table}
\small
\sisetup{uncertainty-mode = separate,
tight-spacing}
\begin{tblr}{hline{1,2,Z},
colspec = {@{} Q[c,m] *{7}{X[c, si={table-format=5.0(1)}]} @{}},
colsep = 3pt,
row{1} = {guard}
}
$N$ & 7 & 6 & 5 & 4 & 3 & 2 & 1 \\
{diametro\\ (\unit{\mm})}
& 48(1) & 63(1) & 74(1) & 88(1) & 95(1) &103(1) & 109(1) \\
{$\cos\theta$\\ (\qty{e-6}{\radian})}
& 99990(1) & 99983(1) & 99977(1) & 99967(1) & 99962(1) & 99955(1) & 99949(1) \\
\end{tblr}
\caption{Caption}
\label{tab:my_label}
\end{table}
\end{document}
