Terminal Table基于Ruby的表格生成器

Terminal Table 是一個用 Ruby 編寫的簡單好用、功能豐富的表格生成器，支持 ASCII 和 Unicode 格式。

用例

構建表格需要基本的陣列信息：

rows = []
rows << ['One', 1]
rows << ['Two', 2]
rows << ['Three', 3]
table = Terminal::Table.new :rows => rows

# > puts table
#
# +-------+---+
# | One   | 1 |
# | Two   | 2 |
# | Three | 3 |
# +-------+---+

可以給構造函數(shù)一個 block，該 block 可以生成 Table 對象，也可以計算實例：

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

在行之間添加分隔符：

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 |
# +-------+---+

定義表格樣式

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

# > puts table
#
# +--------------------------------------+---------------------------------------+
# | Word                                 | Number                                |
# +--------------------------------------+---------------------------------------+
# | One                                  | 1                                     |
# | Two                                  | 2                                     |
# | Three                                | 3                                     |
# +--------------------------------------+---------------------------------------+
