I'm not completely certain I understand the question. Just in case you're asking for something as simple as this ...
select rownum from all_objects where rownum <= 10;You didn't say what version you were using either (shame on you). You could use a collection or a pipeline depending on your version ...
create or replace type ttab_number is table of number;
create or replace function f_collection
    return ttab_number is
    tab_number ttab_number := ttab_number();
begin
    for i in 1 .. 10 loop
        tab_number.extend;
        tab_number(tab_number.count) := i;
    end loop;
    return tab_number;
end f_collection;
select *
from table(f_collection)
create or replace function f_pipeline
    return ttab_number
    pipelined is
begin
    for i in 1 .. 10 loop
        pipe row(i);
    end loop;
    return;
end f_pipeline;
show errors
select *
from table(f_pipeline)
