¿Como esto?
Sugiero utilizar siunitxel paquete. El uso de su tipo de columna Sy su forma de escribir números simplifica significativamente el código de su tabla:
\documentclass{article}
\usepackage{amsmath, amssymb}
\usepackage{booktabs}
\usepackage{siunitx}
\begin{document}
\begin{table}[!htbp]
\sisetup{separate-uncertainty}%
\centering
\begin{tabular}{>{\bfseries}l
S[table-format=-1.2(2)]
S[table-format=-1.1e1]
}
\toprule
Res. & {$\boldsymbol{\beta}$} & {$\boldsymbol{\chi^{2}}$} \\
\midrule
1 & -0.61(32) & 9.1e7 \\
2 & -0.37(12) & 2.5e6 \\
3 & -0.39(19) & 1.0e7 \\
4 & -0.14(13) & 8.0e6 \\
5 & -0.10(12) & 2.3e6 \\
6 & -0.44(13) & 1.8e6 \\
7 & -0.55(16) & 2.0e6 \\
8a & -0.54(16) & 1.9e6 \\

Si desea que la segunda y tercera columna sean más anchas, puede prescribir su ancho de manera similar a como lo hace en el p{...}tipo de columnas: sisetupagregue el ancho deseado de la columna como:
\sisetup{separate-uncertainty,
table-column-width = 22mm}%
En este caso la tabla se convierte en:

Si desea alinear números en una tabla, usesiunitx . Le sugiero que consulte la documentación, en particular los §§ 3.6 y 5.14,material tabular.
