column not invisible in table control

hi,

i want to make 2-3 columns in my table control invisible for some conditions i have done that in the follwing code in PBO but the column is not becoming invisible.

LOOP AT SCREEN.
    IF g_push = 'NM'.
      IF screen-name = 'I_MAT_MASTER-APPR_STORE_BY' .
        screen-invisible = '1'.
        MODIFY SCREEN.
      ENDIF.
    ENDIF.


  ENDLOOP.

kindly suggest how can i make the columns visible or invisible in table control for different conditions.
