Remove a row from a table (Using AJAX)

I have a table with a number of rows. The right most cell contains a

the table.

How can I achieve this?

Assign an id to every row and remove it with Protoype's Element.remove

<% row_id = your_custom_row_id_generating_helper %>
<tr id="<%= row_id>">
  <td><%= link_to_function "Delete", "Element.remove(#{row_id})"%></td>

There's no need to for AJAX if no updated information is needed from the server.
