Disable few record in a table control not all records

Question

Hi 
I have an internal table of   6 rows with table control .first field char 1 (ws_flag) which I am using for line selection of row in the table control .
I have to disable some rows in a table control (user can not select or deselect it).
I don’t want to disable all rows . I just want to disable some rows depending upon the condition .
Loop at screen doesn’t seem to be working .
I already tried the below given code .  how does Screen-name = column name this will besatisfied in  a table control.
Set screen attributes for table control
  loop at zzhb6_0100 with control zhb6ctl
                    cursor zhb6ctl-top_line.
    module modify_screen_0100.
  endloop.
Then:
module modify_screen_0100 output.
  loop at screen.
    if screen-name = 'ZZHB6_SAL_PHASE2_S-ZZMERIT_AMT'.
      if zzhb6_sal_phase2_s-zzself_funded = 'X' or
         zzhb6_sal_phase2_s-zzmed_rec     = 'X' or
         zzhb6_sal_phase2_s-zztr          = 'X'.
        screen-input = '0'.                       "Display
        modify screen.
      endif.
    endif.
    if screen-name = 'ZZHB6_SAL_PHASE2_S-ZZMERIT_AMT_SP'.
      if zzhb6_sal_phase2_s-zzself_funded = 'X'.
        screen-input = '0'.                       "Display
        modify screen.
      endif.
    endif.
  endloop.

When using table control, chances are you have some code like this in the screen flow logic of the screen.
PROCESS BEFORE OUTPUT.
* PBO FLOW LOGIC FOR TABLECONTROL 'I_WOODCAPCON'
* MODULE I_WOODCAPCON_CHANGE_TC_ATTR.
* MODULE I_WOODCAPCON_CHANGE_COL_ATTR.
  LOOP AT   I_WOODCAP
       WITH CONTROL I_WOODCAPCON
       CURSOR I_WOODCAPCON-CURRENT_LINE.
    MODULE I_WOODCAPCON_CHANGE_FIELD_ATTR.
  ENDLOOP.
  MODULE STATUS_0300.
Notice the MODULE I_WOODCAPCON_CHANGE_FIELD_ATTR. in the above code, this is the module which will allow you to change the attributes of the cell per row.  Notice that this MODULE is inside the LOOP statement in the PBO flow logic.
So here is the coding for the module.
module i_woodcapcon_change_field_attr output.
  modify i_woodcap index i_woodcapcon-current_line.
  loop at screen.
    if i_woodcap-level = 'B'
      and  screen-name = 'I_WOODCAP-PDATE'.
          screen-input = '0'.
    endif.
     modify screen.
  endloop.
endmodule.
Notice here that my condition statest that if the LEVEL value for the row is "B", then I want to make the PDATE of the row "not ready for input".   'I_WOODCAP is the name of the internal table associated with the table control.
Help this helps.
