  4 # 这个项目主要目的是字符串的处理，简单格式化输出
  5 tableData = [['apples','oranges','cherries','banana'],
  6              ['Alice','Bob','Carol','David'],
  7              ['dogs','cats','moose','goose']]
  8 # 要求输出如下：
  9 #   apples  Alice  dogs
 10 #  dranges  Bob    cats
 11 # cherries  Carol  moose
 12 #   banana  David  goose
