I don't think sprintf can pad with underscores, but you can use the following
function (untested):
<CODE>
sub pad_with_underscores
{
my ($str, $len) = @_;
return $str . ('_' x ($len - length($str)));
}
</CODE>
Maybe this can also be done with https://metacpan.org/module/Text::Table (which
I should note that I maintain).
