_object_as_table.html.erb

<!--
  Renders an object as an HTML table (developed under Rails 4.0). 
  
  locals:
    * object: The object to render
    * ignore (optional): array of symbols which map to object attributes which won't be rendered in the table
    * calls (optional): array of strings which map to methods to call against the object
    * table_class (optional): class value to use for the table
    * table_id (optional): id to use for the table
    * style (optional): style value to use for the table

  Example usage:

  render partial: "object_as_table",
   locals: {
           object: @user,
           ignore: [:updated_at, :created at],
           calls: [['fullname'], ['is_admin.humanize', 'Is Admin?']],
           table_class: 'tablesorter',
           table_id: 'user',
           style: 'background-color: white'
   }
