I modified your code at modify statement , just check it once,.
DATA : ls_listrow LIKE LINE OF i_final,
ls_stylerow TYPE lvc_s_styl,
ls_styletab TYPE lvc_t_styl.
LOOP AT i_final INTO wa_final.
IF wa_final-light = '1'. "Disabled
ls_stylerow-style = cl_gui_alv_grid=>mc_style_disabled.
ELSEIF wa_final-light = '3'. "Enabled
ls_stylerow-style = cl_gui_alv_grid=>mc_style_enabled.
ENDIF.
ls_stylerow-fieldname = 'CHK'.
APPEND ls_stylerow TO ls_styletab.
INSERT LINES OF ls_styletab INTO TABLE ls_listrow-cellstyles.
"Modify statement need some changes here...
  MODIFY i_final INDEX sy-tabix FROM  ls_list row TRANSPORTING cellstyles.
  CLEAR: ls_listrow, ls_styletab.
ENDLOOP.
