[#5502] - Please add a cloneDataSource() method to JRTableModelDataSource

Would it be possible to add a cloneDataSource() method similar to the one found on JRMapArrayDataSource or JRMapCollectionDataSource.

This would be useful when trying to use the main Report JRTableModelDataSource in a Table (the 1st record in the TableModel is not displayed even when the table is placed inside the title band). Using a new cloned DataSource would prevent this issue.

Currently we have to create our own Custom DataSource and it would be much easier if we could call the clone method when specifying the Table datasource.
