Using \uncover in beamer with a counter

I am using a table in my presentation and it is ordered by date but I want some major dates to be visible on the first slide and all other dates to become visible slide by slide.

I thought it would be a nice way to define a command:

\newcounter{coveredRows}
\newcommand{\uncoverrowauto}[3]{
\uncoverrow{\value{coveredRows}-}{#1}{#2}{#3}
}
\newcommand{\uncoverrow}[4]{
\uncover<#1>{#2} & \uncover<#1>{#3} & \uncover<#1>{#4}\\
}


And I would like to have a table like this:

..
11.06. & ..begin.. & 24\\
25.06.& ..mile stone.. & 26\\
..


So it could become a big table and I am lazy so I would like to auto increment the counter when the rows are uncovered. Unfortunately this doesn't work, it compiles infinite number of slides.

Is there a nice solution for my wish or is the only way to define the slide manually where the different rows are uncovered?

EDIT As mentioned by David, here is a full example of what I have:

\documentclass{beamer}

\begin{document}

\begin{frame}
\titlepage
\end{frame}

\begin{frame}
\frametitle{Outline}
\tableofcontents
\end{frame}

\section{Plan}

\newcounter{coveredRows}
\setcounter{coveredRows}{1}
\newcommand{\uncoverrowauto}[3]{
\uncoverrow{\value{coveredRows} -}{#1}{#2}{#3}
}
\newcommand{
\uncoverrow}[4]{\uncover<#1>{#2} & \uncover<#1>{#3} & \uncover<#1>{#4}\\
}

\begin{frame}
\frametitle{Plan}
\framesubtitle{Dates}

\centering
\begin{tabular}{| c l c |}
\hline
Date    & Explanation & Week\\
\hline\hline
11.06. & Begin of work & 24\\
25.06.& Mile stone of work & 26\\
\uncoverrowauto{24.08.}{Planned end of work}{34}
03.09. & End of work & 36\\
\hline
\end{tabular}

\end{frame}
\end{document}

You improve your chances of an answer by providing a complete example (never mind that it does not work yet) rather than isolated fragments. That way, anybody willing to invest some time for an answer just needs to "make it work" (TM) rather than waste her creative energy on writing up a whole example all by herself. –  user9588 Jun 6 '12 at 9:23
I have a suspicion that the answer will be to put \resetcounteronoverlays{coveredRows} in the preamble, but as David says: without a fully compilable example it's hard to test if this is going to do what you want or not. –  Loop Space Jun 6 '12 at 9:46
Thanks for your comments! I didn't think about that. I will provide a complete example for further readers. But the answer of Andrew seems to do the thing. –  Bertram Nudelbach Jun 6 '12 at 10:02

Here is the full solution, that was mentioned by Andrew. Thanks!!

\documentclass{beamer}

\resetcounteronoverlays{coveredRows}

\begin{document}

\begin{frame}
\titlepage
\end{frame}

\begin{frame}
\frametitle{Outline}
\tableofcontents
\end{frame}

\section{Plan}

\newcounter{coveredRows}
\setcounter{coveredRows}{1}
\newcommand{\uncoverrowauto}[3]{%
\uncoverrow{\value{coveredRows} -}{#1}{#2}{#3}
}
\newcommand{%
\uncoverrow}[4]{\uncover<#1>{#2} & \uncover<#1>{#3} & \uncover<#1>{#4}\\
}

\begin{frame}
\frametitle{Plan}
\framesubtitle{Dates}

\centering
\begin{tabular}{| c l c |}
\hline
Date    & Explanation & Week\\
\hline\hline
11.06. & Begin of work & 24\\
25.06.& Mile stone of work & 26\\
\uncoverrowauto{24.08.}{Planned end of work}{34}
03.09. & End of work & 36\\
\hline
\end{tabular}

\end{frame}
\end{document}


The only thing is, that now the first cell of the rows have a leading space. Therefore I personally would remove the whitespaces in the definition of the two commands. But I'm not sure, if there's a better way, without destroying formatting.

EDIT

I inserted % in the sample above to solve the problem with leading spaces.

Whitespaces can be removed by judicious placement of percent-signs. Try putting % at the end of each line in your new commands. –  Loop Space Jun 6 '12 at 10:15
