Rails 3 XSS Escaping Breaks Plugins

Question

Is there a relatively easy solution to Rails 3 auto escaping to not break view-oriented plugins? I'm using table_builder which has an api along the lines of:

<%= calendar_for(args) do |table| %>
   ...
<% end %>

Unfortunately, rails goes through and escapes all the html generated from that plugin. Is there an easy way to avoid this behavior that doesn't involve me hacking on the plugin itself? I can't really wrap it in a raw() from what I know because its an erb block.
