The Sortable Table is just what it sounds like; it allows you to create a sortable table of information.  Once your information is added to the table, users will be able to sort the rows based on the criteria in the columns.  For example, you could input a list of used cars and users could sort in ascending or descending order based on the information (i.e. Make, model, year, etc..).  With a sortable table you can display any information and provide users with the ability to rearrange the information for easy sorting and viewing.
