Embedding sort director icons in header using SortingHelper?

Hi,

Can anyone recommend a way to embed the use of sort direction icons in
table
headers into the SortingHelper framework, i.e. so one does not have to
manually calcaulate and add the right “down_arrow” / “right_arrow”
images
in?

For example (roughly speaking) I’m doing the follow kind of thing:

   <th><%= link_to "#{ image_tag("arrow_right.gif", {:border => 0}) 

}
Name", @sorter.to_link(“NAME”, params) %>

Thanks
Greg

PS. I should say I’m doing something like this at the moment…

<% if params[:sort] == "NAME" %>
    <th><%= link_to "#{ image_tag("arrow_down.gif", {:border => 0}) 

}
Name", @sorter.to_link(“NAME”, params) %>
<% else %>

<%= link_to “#{ image_tag(“arrow_right.gif”, {:border => 0})
}
Name”, @sorter.to_link(“NAME”, params) %>
<% end%>
