Perhaps the easiest way to do this is to use
\multicolumn{1}{c}{label} for each of your labels on the top.

For Jonathan's problem:

\begin{tabular}{c|c|c|}
\multicolumn{1}{c}{}&\multicolumn{1}{c}{label1}&\multicolumn{1}{c}{label2}\\
\cline{2-3}
row1 & cell 1 & cell 2\\
\cline{2-3}
row2 & cell 3 & cell 4\\
\cline{2-3}
\end{tabular}

For Alain's problem:

\begin{tabular}{|c|c|c|}
\cline{2-3}
\multicolumn{1}{c|}{} & label1 & label2\\
\hline
row1 & cell 1 & cell 2\\
\hline
row2 & cell 3 & cell 4\\
\hline
\end{tabular}
