Update: The default arguments to split are sufficient: split $_ around whitespace.

The format string (first argument) to printf is as follows:
% indicates the start of a format specifier, a value which follows the format string will be "plugged-in" and formatted into this position.
- means left justify the field
10 (or 7 or 8) is the minimum field width. Shorter fields will be padded with spaces, longer will be displayed intact (data will not be lost).
s indicates the field is a string
