How would you do this?

I need to build a configuration tool. This tool will show a database table layout on the right
and an XML tree structure on the left. The user will drag and XML node and drop it on top of the
table column that corresponds to the XML node in order to build a relationship between the XML node
and the table column. For example, let's say I have this layout.

XML Tree                                  Column Name
------------------                        ---------------
<AvailableBatch>                          id_product       
  <Available>                             id_supplier      
    <Sku />                               id_manufacturer  
    <Part />                              ean13            
    <Qty />                               quantity         
    <Time />                              price            
  </Available>                            wholesale_price  
</AvailableBatch>                         reference        
                                          supplier_reference
                                          location         
                                          weight           
                                          out_of_stock     
                                          active           
                                          date_add         
                                          date_upd  
      

I want the user to be able to drag the Sku node and drop it on the supplier_reference "column" to
"relate" the two. This is going to be used for an import utility that will be generic enough that
a user can build his own configuration and his XML will be imported into his database based on the
configuration.

I already have some thing similar using the dragtable plugin here but it was using only one row
because it is used to reorder the columns in one table:dragtable

Any other ideas on what I should use or if there are any ready-made components that can do the job?
