Enabled and Desabled Checkboxes in an ALV Grid

Question

Hallo Everybody!
I have an ALV grid made with CL_GUI_ALV_GRID methods.
As the first field of the list there's an editable checkbox that allows to make certain operations on the toolbar with the selected cells.
Now I need to disable some of these checkboxes only, for a precise kind of conditions of the IT_OUTTAB.
How can I do it?
Thanks in advance.

This is some example code that does something close to what you are asking.
The output table definition
DATA: BEGIN OF gt_outtab OCCURS 0.
        INCLUDE STRUCTURE zscemp_wk.
DATA: cellstyles    TYPE lvc_t_styl.
DATA: END OF gt_outtab.
The logic that sets the field to disabled/enabled based on conditions.
*&      Form  adjust_editables
FORM adjust_editables USING    pt_list LIKE gt_outtab[].
  DATA: ls_listrow  LIKE LINE OF pt_list.
  DATA: ls_stylerow TYPE lvc_s_styl.
  DATA: ls_styletab TYPE lvc_t_styl.
  LOOP AT pt_list INTO ls_listrow.
    REFRESH ls_listrow-cellstyles.
    REFRESH ls_styletab.
    IF edit_mode EQ 'D'.
      ls_stylerow-fieldname = 'BRANCH'.
      ls_stylerow-style = cl_gui_alv_grid=>mc_style_disabled.
      APPEND ls_stylerow TO ls_styletab.
    ENDIF.
    ls_stylerow-fieldname = 'EMPNO'.
    IF  ls_listrow-empno IS INITIAL
    AND edit_mode EQ 'E'.
      ls_stylerow-style = cl_gui_alv_grid=>mc_style_enabled. "<== here setting to enabled
    ELSE.
      ls_stylerow-style = cl_gui_alv_grid=>mc_style_disabled.. "<== here setting to diabled
    ENDIF.
    APPEND ls_stylerow TO ls_styletab.
    INSERT LINES OF ls_styletab INTO TABLE ls_listrow-cellstyles.
    MODIFY pt_list FROM ls_listrow.
  ENDLOOP.
ENDFORM.                    " adjust_editables
