Table cntrol field to be display/Change only For each record

Question

Hi all,
How to set a particular Field in table control either as display only or
change only for <b>each row</b> based on certain condition.I need to set this property for each record in table control not for the entire coloumn?.I know the procedure for setting up an entire coloumn in table control either as diplay or change only using <b>Loop at screen</b> statement.
Conditions:
If Material is batch managed:
itab-batch field has to be <b>Display only</b> mode.
if material is not batch managed:
itab-batch field has to be <b>change mode</b>.
<b>O/p of Table Control :</b>
Material     Batch
1000         Display only
2000        Change only
8000        Change only
3500        Display only
3600        Display only

Hi Ravi,
          Thanks for your reply.I have put the code as u said. It is modifying the whole coloumn insted of  modifying Current row of the coloumn.
I have tried to modify the screen property using  Table control attributes (TC-COLS).The following commented code is that logic.Even that also doing the same thing.Can yoy please tell me how to do it.
MODULE tc_get_lines OUTPUT.
LOOP AT SCREEN.
    IF screen-name = 'X_ZPINV-CHARG'.
      IF fg_batch = ' '.
        screen-input = 0.
      ELSE.
        screen-input = 1.
      ENDIF.
    ENDIF.
    MODIFY SCREEN.
  ENDLOOP.
LOOP AT tc-cols INTO tc_wa
  WHERE screen-name = 'X_ZPINV-CHARG'.
   IF x_zpinv-matnr IS NOT INITIAL.
     CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'
       EXPORTING
         input  = x_zpinv-matnr
       IMPORTING
         output = v_matnr.
     SELECT SINGLE * FROM marc WHERE matnr = v_matnr
     AND werks = w_plant.
     IF marc-xchar IS INITIAL.
       tc_wa-screen-input = 0.
     ELSE.
       tc_wa-screen-input = 1.
     ENDIF.
     MODIFY tc-cols FROM tc_wa INDEX sy-tabix."    transporting screen-input
   ENDIF.
ENDLOOP.
ENDMODULE.                    "TC_GET_LINES OUTPUT
