This is very much like adding sub-documents. Use the @RUNWORDMACRO() function to create a Word macro for a table based on TeLiTab input (when required create the TeLiTab first with the TELITAB#() function). In the template add the reference to the parameter that creates the table macro and also add this parameter to the relation that uses the template.
