Sorting a listing page

Rails
1

Hi
I have a list page for users. I am using will_paginate for
pagination. So an example is

full_name(f_name+l_name) email unit(this an integer colum is
user.buildng.unit)

Clinton Trone [email protected] 2
Evette Pace [email protected] 2
Brett B [email protected] 10
…

     My requirement is to sort by any of the headings ie

first_name, email or unit on clicking them. Also I need Alphabetical
sorting .Like there will be
All,A,B,C …Z,Other
in the list page. Then on clicking suppose D the paginated list has
to sorted by letter ‘D’ like that. I have no idea how to implement this.
Please help

Thanks in advance
Tom

Hi
I still could not get an exact choice. I found this
http://www.2dconcept.com/jquery-grid-rails-plugin

But suppose if have a column like full_name but it is not a db

column ( i have db columns firstname and lastname) then what I will do?
If anybody has any other choice than please help.

Thanks
Tom
