Rails - Feb 2006 - Ajax and tables

Guys,

I want to be able to update the contents of a table without dedrawing 
the entire thing. Basically, if the user clicks on the 2nd column then i 
want to turn that cell red, the 3rd green and the 4th blue.

I have the table drawing correctly now but not updating correctly. I 
can''t get the update to work on the div unless its inside the table 
cell. I was hoping to have the div around the entire row but when I do 
that, the contents of the ajax update show up above the table.

Does anyone have a good suggestion of how to do this?


Code snippets below

Thanks, Gareth

Here row, done for each feature.

  <tr>
    <td><%=h feature.description %></td>

	<% if @session[:vendor] %>
		<% impl = feature.implementation( @session[:vendor].id ) %>
		<div id=''<%= feature.id  %>''>
		<td bgcolor =<%= impl.supports( FeatureImplementation::YES ) ?
''green''
: ''white'' %>>
			<%= link_to_remote "click",
				:url => {:action => ''set_implementation'', :id =>
impl.id, :value =>
FeatureImplementation::YES },
				:update => feature.id %>
		</td>

		<td bgcolor =<%= impl.supports( FeatureImplementation::SPECIAL ) ? 
''yellow'' : ''white'' %>>
			<%= link_to_remote "click",
				:url => {:action => ''set_implementation'', :id =>
impl.id, :value =>
FeatureImplementation::SPECIAL },
				:update => feature.id %>
		</td>
		<td bgcolor =<%= impl.supports( FeatureImplementation::CUSTOM ) ? 
''brown'' : ''white'' %>>
			<%= link_to_remote "click",
				:url => {:action => ''set_implementation'', :id =>
impl.id, :value =>
FeatureImplementation::CUSTOM },
				:update => feature.id %>
		</td>
		<td bgcolor =<%= impl.supports( FeatureImplementation::NO ) ?
''red'' :
''white'' %>>
			<%= link_to_remote "click",
				:url => {:action => ''set_implementation'', :id =>
impl.id, :value =>
FeatureImplementation::NO },
				:update => feature.id %>
		</td>
		</div>
	<% end %>
    <td><%= link_to ''Edit'', :action =>
''edit'', :id => feature if
@session[:user] %></td>
    <td><%= link_to ''Destroy'', { :action =>
''destroy'', :id => feature },
:confirm => ''Are you sure?'' if @session[:user]
%></td>

  </tr>

And the action in the controller...

  def set_implementation
    puts ''set_implmplementation''
    impl = FeatureImplementation.find( params[:id] )
    impl.value = params[:value]
    impl.save()

    render_text "X"  # this should return the entire row
  end
