module FatTable
  # A subclass of Formatter for rendering the table as a Ruby Array of Hashes.
  # Each row of the Array is a Hash representing one row of the table with the
  # keys being the symbolic form of the headers. Each cell is a value in a row
  # Hash formatted as a string in accordance with the formatting directives. All
  # footers are included as extra Hashes of the output. AoaFormatter supports no
  # +options+
