Avoidance of ORA-14511 in partitioned tables

We wish to elimnate tablespace TS_EXF

We have a partitioned table EXF.PART_TABLE

We can move the partiones by

ALTER TABLE EXF.PART_TABLE MOVE PARTITION PART01 TABLESPACE TS_EXF_PART;

This leaves part_table itself still in TS_EXF

When we try this

    ALTER TABLE EXF.PART_TABLE MOVE TABLESPACE TS_EXF_PART;

we get

ORA-14511: cannot perform operation on a partitioned object

which I would assume means we better not eliminate TS_EXF

My question is, ¿how do we disassociate the table exf.part_table from the tablespace TS_EXF in order that we can delete the Tablespace in question?
