How to hide the table control column in module pool

Question

Dear Experts,
Please help me on this
I have 2 screens 9000 and 9001 . In screen 9000 I have 2 radio buttons if I select the 2nd radiobutton then the screen  9001 should display inthat some column has to be hide inthe table control. I have used this code but still it is not hiding please help me on that
I used this code in PBO of 9001 screen
LOOP AT SCREEN.
    IF wopr = 'X'.
      IF screen-group2 = 'ABC'.
        IF screen-name = 'ZMMT_EKKO-MATNR' or screen-name = 'ZMMT_EKKO-BANFN'.
        screen-active = ''.
          screen-invisible = '1'.
          screen-input = ''.
          MODIFY SCREEN.
        ENDIF.
      ENDIF.
    ENDIF.
  ENDLOOP.
Even I tried this code also in the same screen 9001
loop at tbl_rfq-cols into cols.
IF wopr = 'X'.
IF screen-group2 = 'ABC'.
IF cols-screen-name = 'ZMMT_EKKO-MATNR' or cols-screen-name = 'ZMMT_EKKO-BANFN'.
cols-screen-input = '0'.
cols-invisible = '1'.
endif.
MODIFY tbl_rfq-cols FROM cols INDEX sy-tabix.
endif.
endif.
endloop.

Hi Balaji,
To hide a column in a table control on screen.
In the PBO of the screen, inside
loop with control <tab_ctrl_name>.
module modify_tab.
endloop.
Say for a column, you take group1 as 'ABC'.
In this module you can use the group for the input/output fields and the display/hide them as per your requirements.
if <condition>.
loop at screen.
  if screen-group1 = 'ABC'. "say textbox (column for a table) has group1 as ABC
   screen-invisible = 'X'. "hide a column
   screen-active = ' '.
  endif.
  modify screen.
elseif <condition>.
loop at screen.
  if screen-group1 = 'ABC'. "say textbox (column for a table) has group1 as ABC
   screen-invisible = ' '. "display a column
   screen-active = 'X'.
  endif.
  modify screen.
endif.
Similarly, you can use this code for other columns also.
Hope this solves your problem.
