I'm trying to align numbers by a decimal point in LaTex. I know this has already been answered, but what I can't figure out is how to center justify the labels around the decimal point.
\begin{tabular}{r@{}l r@{}l}
\hline
\multicolumn{2}{c}{Landings (mton)} & \multicolumn{2}{c}{Landings (mton)} \\
73.&57&877.&36\\
1.&28&5.&19\\
\hline
\end{tabular}
