\bfseries for math mode (whole table row in bold)

Question

I've got this neat little snippet from question Make first row of table all bold:

\documentclass{article}
\usepackage{array}
\newcolumntype{$}{>{\global\let\currentrowstyle\relax}}
\newcolumntype{^}{>{\currentrowstyle}}
\newcommand{\rowstyle}[1]{\gdef\currentrowstyle{#1}%
  #1\ignorespaces
}

\begin{document}
\begin{tabular}{$l^c^r}
\rowstyle{\bfseries}
a & a & a \\
b & b & b \\
c & c & c \\
\end{tabular}
\end{document}

It works perfectly fine in text mode. However, if I've got a math mode in my table like in the following snippet, this won't work.

\begin{tabular}{$l^c^r}
\rowstyle{\bfseries}
a & $1.33*10^5$ & a \\
b & b           & b \\
c & c           & c \\
\end{tabular}

The two a are bold, but the equation isn't bold. However if I'm using

\begin{tabular}{$l^c^r}
\rowstyle{\bfseries}
a & \textbf{$1.33*10^5$} & a \\
b & b                    & b \\
c & c                    & c \\
\end{tabular}

the equation is rendered bold just perfectly. Do I need another command for this to work? I've trying to typeset one row with ~17 columns (12 math mode) bold in about 20 tables. I would really like not to put every equation in a \textbf.

Using

\begin{tabular}{$l^c^r}
\rowstyle{\textbf}
a & $1.33*10^5$ & a \\
b & b           & b \\
c & c           & c \\
\end{tabular}

Ends in an error You can't use a prefix with `\aftergroup' in the next line.

Answer 1

That was quick, I am a dimwit. The solution is to add \boldmath:

\begin{tabular}{$l^c^r}
\rowstyle{\boldmath\textbf}
a & $1.33*10^5$ & a \\
b & b           & b \\
c & c           & c \\
\end{tabular}
