Question

如何格式化列我有一個數組內的Ruby數組看起來象下面這樣：

更多的數據信息是這裏https://gist.github.com/theCrab/6064789

列標題是風格，顏色， 大小，降序，數量，min_qty，req_qty，個root_sku，offset_size

 
[ 
["UD/BOYS-TR/SENIOR/STANDARD", "*BLACK/2SHORT LEG", "28\" W", "29\"LEG STD MENS TROUSER", -10, 4, 14, "00001955", 1], 
["UD/BOYS-TR/SENIOR/STANDARD", "*BLACK/2SHORT LEG", "30\" W", "29\"LEG STD MENS TROUSER", -14, 6, 20, "00001955", 2], 
["UD/BOYS-TR/SENIOR/STANDARD", "*BLACK/2SHORT LEG", "32\" W", "29\"LEG STD MENS TROUSER", -29, 6, 35, "00001955", 3], 
["UD/BOYS-TR/SENIOR/STANDARD", "*BLACK/3REG LEG", "28\" W", "31\"LEG STD MENS TROUSER", 0, 3, 3, "00001976", 1], 
["UD/BOYS-TR/SENIOR/STANDARD", "*BLACK/3REG LEG", "30\" W", "31\"LEG STD MENS TROUSER", -12, 5, 17, "00001976", 2], 
["UD/BOYS-TR/SENIOR/STANDARD", "*BLACK/3REG LEG", "32\" W", "31\"LEG STD MENS TROUSER", -6, 6, 12, "00001976", 3] 
] 

我想打印一個很好的格式化的表格看起來象下面這樣：

style | colour | size | desc | qty | min_qty | req_qty | root_sku 
----------------------------------------------------------------- 
standd| red | 28 W | N/a | 4 | 5  | 1  | 00001955 
     |  | 30 W | N/a | 9 | 5  | 4  | 00001955 
     |  | 36 W | N/a | 10 | 5  | 5  | 00001955 
     | blue | 28 W | N/a | 4 | 5  | 1  | 00001955 
     |  | 30 W | N/a | 9 | 5  | 4  | 00001955 
     |  | 36 W | N/a | 10 | 5  | 5  | 00001955 
fitted| red/blu| 28 W | N/a | 4 | 5  | 1  | 00001954 
     |  | 30 W | N/a | 9 | 5  | 4  | 00001954 
     |  | 36 W | N/a | 10 | 5  | 5  | 00001954 
     | blue | 28 W | N/a | 4 | 5  | 1  | 00001954 
     |  | 30 W | N/a | 9 | 5  | 4  | 00001954 
     |  | 36 W | N/a | 10 | 5  | 5  | 00001954 

我怎樣才能最好通過陣列運行，並完成這一壯舉？

Answer 1

Ruby有一個字符串格式化功能，我認爲它源自舊的C風格sprintf函數。 http://www.ruby-doc.org/core-2.0/Kernel.html#method-i-sprintf和http://ruby-doc.org/core-2.0/String.html#method-i-25

在String類中，您使用%方法並傳入一個數組。

outer_array.each do |inner_array| 
    puts ('%6s|%8s|%5s|%6s|%4d|%8d|%6d|%10d' % inner_array) 
end 

（附註：我只是猜的格式，所以你需要改進的必要）
