ALV - CL_SALV_TABLE - Top of page

I need to find a print-top-of-page type event for the ALV class cl_salv_table. This would be similar to the event print_top_of_page for class cl_gui_alv_grid. What this does is allows you to create the report header, the header that will be printed or displayed if the ALV is viewed in list format.

I found the event top_of_page in the class CL_SALV_TABLE but I do not see how I can set the heading.

Any ideas?
