The format qualifier may be used to specify a printf-style format string for the
named columns; in this case, all of the columns must have the same data type. The format
string should contain a width field, to ensure proper alignment of text, e.g.,
%s. The useDefaultFormat qualifier directs that sddsprintout
use its own default format for the data type in question, as opposed to any format that might
be specified in the SDDS header.
The label qualifier can be used to specify the column label in the printout (by default, the column name is used); the label may be edited using the editLabel qualifier and a standard editing sequence.
If the endsLine qualifier is given, a line break is issued after the last column of the list is printed. The blankLies qualifier may be used to specify that one or more blank lines be emitted following such a line break.
Any number of -columns options may be given.
