extract_columns(data : Array(Array(String | Nil))) : Array(Column)

Extracts Column objects from the provided data primarily for use use by this class, but you may find it useful too.

Source

format(options : Hash(Symbol, String | Bool) = Hash(Symbol, String | Bool).new) : String

Formats the data into a textual table. By default it will:

start each row with "| "
end each row with " |"
separate each item with " | " These defaults can be overridden by specifying :left_border, :right_border, or :divider (respectively) in the options.

By default it assumes the first row is a header. To disable the divider under the first row set options[:show_header] = false To change the character used for the divider set options[:header_divider] = <any single character>

Example: [["things", "stuff"],["a", "b"], ["c", nil]] Would become

things	stuff
a	b
c
