Creating dynamic objetcs

I need to be able to create an internal table with records having type ref to cl_dd_table_element.

eg. begin of i_tab occurs 0,

tabl type ref to cl_dd_table_element,

end of i_tab.

Also, I need to be able to populate i_tab-tabl with values 'tbl1', 'tbl2', 'tbl3', etc.

Is it possible to do this using field symbols?
