Question

我有这个哈希，包含哈希的数组：

{ 
 "Company1" => [
   { "name" => "test1",   "count" => 2},
   { "name" => "test123", "count" => 3}
 ],
 "Company2" => [
   { "name" => "test33",  "count" => 2},
   { "name" => "test453", "count" => 3},
   { "name" => "test342", "count" => 2},
   { "name" => "test90",  "count" =>3}
 ]
}

我想迭代它，所以我可以使格式以表格格式打印出来。表格式可能是这样的：

Company  | Name   |   Count
Company1
          test1       2
          test123     3
Company2
          test33      2
          test453     3
          test342     2
          test90      3

那么我如何迭代包含哈希数组的ruby哈希。

Answer 1

尝试这样的事情：

hash.each do |company, elements|
  puts "#{company}\t\t"
  elements.each do |v|
    puts "\t#{v['name']}\t#{v['count']}"
  end
end

如何迭代数组哈希以创建表？
