Rails - Oct 2007 - sort & scrollable table

So I have a show.rhtml that displays XML data generated from perl. The
column headers are the element tags in the XML, enclosing the data. I
have two questions

1) How would I make the columns sortable when a user clicks on the
column header; ASC/DESC?

2) How would you create a text box that would allow me to filter the
results? For instance, if a column was labeled "State", I could switch
the filter to state, and Just type a "T", and only rows with a state
starting with a T would be displayed.

Is there a plugin or an easy way to do these two things?

Here is my table ion the show.rhtml

<table class="standard">

    <thead>
      <tr>
<%
  link_index = nil
  @report.columns.each do |col|
    if(col.name.downcase == ''link'' || col.name.downcase ==
''label'')
      link_index = col.name

-%>
        <th>Drill Down Avail</th>
<%
    else
-%>
    <th><%= col.human_name %></th>

<%
    end
  end
-%>
      </tr>
    </thead>
    <tbody>
      <%= ''<p class="no_results">Sorry, no results
were found with the
supplied parameters</p>'' if @report.rows.size == 0 %>
<%
  @report.rows.each do |row|
    if link_index
-%>
      <tr class="clickable <%= cycle("", "shade")
-%>"
onclick="window.location=''<%= url_for :action =>
''drill_down'', :params
=> { :url => CGI.escape(row[link_index])} %>''">
<%
    else
-%>
      <tr class="<%= cycle("", "shade")
-%>">
<%
    end
    @report.columns.each do |col|
      if (col.name != link_index)
-%>
        <td><%= row[col.name] %></td>
<%
      else
-%>
        <td><%= link_to ''+'', :action =>
''drill_down'', :params => { :url
=> CGI.escape(row[link_index])} %></td>
<%
      end
    end
-%>
      </tr>

will_paginate MAY do what I need, but I am not reading from a table. I 
do a call to a perl script which returns an XML stream/response that 
ruby catches.

the examples I am seeing is reading from a table. How would I do set 
this up when the data is coming from an XML stream and not a database?
