Center align columns in table ignoring minus signs?

I have some tables of numbers, most of which are small (0, 1, -1), but occasionally I have fractions. If I just has 0, 1, -1's I'd right align so the $-$ signs will line up, but the fractions throw things off. Center align doesn't look great either, nor does left align. Here is a small example of a right and center align:

begin{tabular}{rr}

$frac 1{24}$ & $-frac 1{24}$ \

$1$ & $-1$ \

$-1$ & $0$ \

end{tabular}

quad

begin{tabular}{cc}

$frac 1{24}$ & $-frac 1{24}$ \

$1$ & $-1$ \

$-1$ & $0$ \

end{tabular}

Can I center align the numbers without the signs, so the top two rows will look like they do on the right in the example above, and the bottom two rows will look like the do on the left in the above example?

With phantom you can insert an invisible -:

documentclass{article}



begin{document}

begin{tabular}{cc}

$phantom{-}frac 1{24}$ & $-frac 1{24}$ \

$phantom{-}1$ & $-1$ \

$-1$ & $phantom{-}0$ \

end{tabular}

end{document}

If your table contains only (mostly) math, you might want to use array instead of tabular.
