       Pascal's triangle spacing is off. Need DigitCount?

```I'm trying to get the same spacing between the _center points_ of each of
the numbers in the Pascal triangle, so that each entry in a row is centered
properly underneath the corresponding two entries in the row above. Instead,
all the spacing options for Row[ ] seem to just apply to the spacings
between numbers.

It looks like I would have to calculate the length (i.e., number of digits)
of each entry as I go through the table. Is DigitCount the best function to
use here? I.e., won't slow things down too much? Or is there a faster way?

Thanks for any help.

pascalTrngl2[n_] :=
Module[
{max, sp},

max = Max[Table[Binomial[n, j], {j, 0, n}]];
sp = Round[N[Log[10, max], 5]];

Column[
Table[
Row[
Table[Binomial[i, j], {j, 0, i}],
Invisible[sp]
],
{i, 0, n}
],
Center
]
]
