Hibernate automatically creates new tables if there are corresponding POJOs.

If you know how to write/read to/from an existing table using Hibernate, then you can easily create a table.
Step#1: Create the POJO class for the table to be created.
Step#2: Write the (NewTable).hbm.xml file of this table/entity.
Step#3 (optional): Change the property "hbm2ddl.auto" value to "create" in the hibernate.cfg.xml (generally we use update).
Step#4: Add the mapping resource of the NewTable in hibernate.cfg.xml
Step#5: Write a sample program to add data to your NewTable... to make sure it's working.

If all the configuration stuff is good and the execution goes as expected, check the database for the table and we should be able to find it with the sample records added.
