How to remove tool bar from an ALV table

I have a screen 100 in which there are few text fields, push buttons, and a ALV container. This ALV output is just to display an internal table. I use below codes:

module PBO_100 output.

SET PF-STATUS 'MAIN_100'.

if g_container is initial.

create object g_container

exporting container_name = 'GG_CONTAINER'.

create object grid

exporting i_parent = g_container.

endif.

call method grid->set_table_for_first_display

exporting i_structure_name = p_table

changing it_outtab = <ntab2>[].

endmodule.

It works but I don't need a tool bar (such as details, sort, find, ...) above the ALV table. How can I remove it?

Thank you very much.
