Create datasheet in MDE

My application creates a datasheet on the fly. Users make a selection from a
set parameters including column names, sort order, etc and the code
populates a querydef with the set of columns selected by the user.

This works fine in an MDB. The equivalent MDE crashes - "That command isn't
available in an MDE database"

Please tell me how to add/delete columns from a querydef in an MDE file?
