How do I read and print a generic internal table?

Question

I'm pretty new to this. I'm currently studying abap for my job and I have a problem that I can't seem to work out. How would I go about creating a Function Module that takes any kind of internal table and write it to the screen? I'm looking for a very generic solution that can work with any kind of internal table as input.

This is the exact reason SAP has developed ALV (ABAP List Viewer). One of the shortest way to display any (non-nested) table is the following.

  DATA: go_alv  TYPE REF TO cl_salv_table.

  CALL METHOD cl_salv_table=>factory
    IMPORTING
      r_salv_table = go_alv
    CHANGING
      t_table      = itab.

  go_alv->display( ).
