Interference between \onslide and \setbeamercovered{transparent}

Question

I'm trying to use \onslide in a table, but since I have the option \setbeamercovered{transparent} in the preamble, it does not produce the overlay of columns.

Here is my example:

\documentclass[xcolor=pdftex,dvipsnames,table]{beamer}
\setbeamercovered{transparent}

\begin{document}

\begin{frame}
    \frametitle{Test 1}

    \begin{itemize}
        \item<1-> A
        \item<2-> B
    \end{itemize}
\end{frame}

\begin{frame}
    \frametitle{Test 2}
    \begin{table} \caption{Test}
        \begin{tabular}{lc<{\onslide<2->}c<{\onslide}}
             A & 1 & 2 \\
             B & 1 & 2 \\
        \end{tabular}
    \end{table}
\end{frame}

\end{document}

If I comment the second line it works, otherwise it doesn't.

Answer 1

try \onslide+:

    \begin{tabular}{lc<{\onslide+<2->}c<{\onslide}}

and by the way, arguments for xcolor must be in parentheses:

\documentclass[xcolor={dvipsnames,table}]{beamer}
