我想简单地在表中输出一些结果,而不存在任何偏移问题。为了清晰起见,不要担心只是伪代码的foreach和值的输出。
print "\n ______________________________________________________";
print "\n | |";
print "\n | Title |";
print "\n +______________________________________________________+";
print "\n | | |";
print "\n | City | Size |";
print "\n |__________________________|___________________________|";
#Sort by highest scores
################################
foreach (city, size)
{
print "\n | (city(value)";
print "| (size(value)";
}
任何想法?

它很少被使用,但Perl具有内置的能力来创建这些类型的forms。
基本上,您使用规范来说明您希望如何格式化这些表,以及使用format
语句放置这些表中的信息的位置。然后,使用Perl write
语句写入该格式。您也可以指定表格的页眉和页脚。

我建议你使用
substr
覆盖模板行的正确部分。
use strict;
use warnings;
my %data = (
Birmingham => 1_000_000,
Bristol => 430_000,
Manchester => 110_000,
);
print " ______________________________________________________\n";
print " | |\n";
print " | Title |\n";
print " +______________________________________________________+\n";
my $template =
" | | |\n";
print $template;
while (my ($city, $size) = each %data) {
my $line = $template;
substr $line, 12, length $city, $city;
substr $line, 39, length $size, $size;
print $line;
}
print " |__________________________|___________________________|\n";
