Is it possible to transpose an html table (without javascript). I m generating a table with rails (and erb) from a list of object.

In Rails, we can respond_to do |format| format.html format.json { render :json => @data } end so it knows to automatically show the @data in json format, but when it is xml, it needs to be format.xml { render :xml => @data.to_xml } why does it need to explicitly convert @data into XML? Can't it be just like json's case? to...
