As far as I can understand, that's exactly the event you need. You can get a reference to the created link from the event argument. Then you can access the origin and destination tables through the link's Origin and Destination properties respectively. The table rows the link is attached to can be obtained through the OriginIndex and DestinationIndex properties.

For example, the following code modifies the destination cell of a newly created link with the value of the origin cell (in a table with two columns):

(e.Link.Destination as TableNode)[0, e.Link.DestinationIndex].Text =
      (e.Link.Origin as TableNode)[1, e.Link.OriginIndex].Text; 

I hope this helps.
