@dbtsai This was what I started out with initially as well. The main challenge I faced was this error: `org.apache.spark.sql.catalyst.analysis.UnresolvedException: Invalid call to dataType on unresolved object ...`. I just tried running your implementation of `withField` against the unit tests in this PR and it's giving me the same error. Is there anything special you did to get around it?
