将表格中带括号的部分的小数对齐

Question

我想创建下表，并且有以下几个问题：

在表格中，我希望将“观测值”上方的小数对齐，包括括号中的数字和 ，***同时希望 R^2 和观测值位于中间（不与小数对齐）。有什么有效的方法可以实现吗？

\begin{table}[h] \centering
\sisetup{input-symbols = {( )}}
\captionsetup{font=tenpt}
   \caption{Example table}
\begin{tabular}{@{}l *{5}{S[table-format = +5.5]}@{}}
\toprule
Groups & {15-30}  & {31-50} & {31-59}  & {50-15} & {$\geq$ 15} \\
\hline


Tea  & 0.10 & 0.50  & 0.10 & 0.60  & 0.60 \\

Apple & 3,521.20^{***} & 2,560.61^{**} & 116.15 & 212.01^{***} & -53.20^{**} \\

   & (562.56) & (1,256.15)  & (563.16) & (91.61) & (19.15)  \\

\hline 
Observations & 566 & 566 & 566 & 566  & 566  \\

$R^{2}$ & 0.01 & 0.01 & 0.03 & 0.05 &0.03  \\
\bottomrule 
\end{tabular}
\end{table}

下表是我在 Overleaf 中得到的版本，带有警告“在第 xxx 行检测到过满的 \hbox（太宽 4.23pt）...”：

siunitx下面的代码应该可以与overleaf 当前使用的旧版本兼容：
