found no similar issues.
   
   
   ### Description
   
   Now we have some outer table function like `explode_bitmap`, and some 
non-outer function like `explode`.
   I try to make all table functions behave as non-outer, and support `outer` 
combinator to automaticly build outer version.
   example:
   ```sql
   MySQL [test]> select e1 from (select 1 k1) as t lateral view 
explode_numbers(0) tmp1 as e1;
   Empty set (0.009 sec)
   
   MySQL [test]> select e1 from (select 1 k1) as t lateral view 
explode_numbers_outer(0) tmp1 as e1; 
   +------+
   | e1   |
   +------+
   | NULL |
   +------+
   ```
