#sortable_table(options = {}) ⇒ Object

Helper method to generate a sortable table in the view

usage: <%= sortable_table(optional_params) %>

optional_params:

:paginate - Whether or not to display pagination links for the table. Default is true. :partial - Name of the partial containing the table to display. Default is the table partial in the sortable

plugin: 'sortable/table'

If you choose to create your own partial in place of the one distributed with the sortable plugin 
your partial has the following available to it for generating the table:
  @headings contains the table heading values
  @objects contains the collection of objects to be displayed in the table

:search - Whether or not to include a search field for the table. Default is true.
