Terminal Table基于 Ruby 的表格生成器

Terminal Table 是一个用 Ruby 编写的简单好用、功能丰富的表格生成器，支持 ASCII 和 Unicode 格式。

用例

构建表格需要基本的阵列信息：

rows = []

rows << ['One', 1]

rows << ['Two', 2]

rows << ['Three', 3]

table = Terminal::Table.new :rows => rows



# > puts table

#

# +-------+---+

# | One   | 1 |

# | Two   | 2 |

# | Three | 3 |

# +-------+---+

可以给构造函数一个 block，该 block 可以生成 Table 对象，也可以计算实例：

table = Terminal::Table.new do |t|

  t.rows = rows

end



table = Terminal::Table.new do

  self.rows = rows

end

一行一行地添加：

table = Terminal::Table.new do |t|

  t << ['One', 1]

  t.add_row ['Two', 2]

end

在行之间添加分隔符：

table = Terminal::Table.new do |t|

  t << ['One', 1]          # Using << (push) as an alias for add_row

  t << :separator          # Using << with :separator as an alias for add_separator

  t.add_row ['Two', 2]

  t.add_separator          # Note - this version allows setting the separator's border_type

  t.add_row ['Three', 3]

end



# > puts table

#

# +-------+---+

# | One   | 1 |

# +-------+---+

# | Two   | 2 |

# +-------+---+

# | Three | 3 |

# +-------+---+

定义表格样式

table = Terminal::Table.new :headings => ['Word', 'Number'], :rows => rows, :style => {:width => 80}



# > puts table

#

# +--------------------------------------+---------------------------------------+

# | Word                                 | Number                                |

# +--------------------------------------+---------------------------------------+

# | One                                  | 1                                     |

# | Two                                  | 2                                     |

# | Three                                | 3                                     |
