PaddedForm[expr, n] prints with all numbers in expr padded to leave room for a total of n digits.
PaddedForm[expr, n, f] prints with approximate real numbers having exactly f digits to the right of the decimal point.
By default, PaddedForm pads with spaces on the left to leave room for n digits.
PaddedForm pads with zeros on the right in approximate real numbers.
The length n specified in PaddedForm counts only digits, and not signs, breaks between digits, and so on.
PaddedForm takes the same options as NumberForm, but with some defaults different.
You can use PaddedForm to align columns of numbers.
PaddedForm acts as a "wrapper", which affects printing, but not evaluation.
