Nested structure when using FM XXL_SIMPLE_API

Question

I use this logic to fill in the headings before calling the FM xxl_simple_api in one of my programs. Is it possible to have nested structure(for <b>i_tab</b> in my code) and still use same kind of logic to fill in the headings? Not sure if this Fm would display data correctly when there is a component of strucutre type. I tried it, the field was blank with no contents in excel.
  DATA : nlines TYPE i,
         tempfile LIKE gxxlt_f-file,
         descr_ref TYPE REF TO cl_abap_structdescr,
         header LIKE gxxlt_v OCCURS 0 WITH HEADER LINE,
         it_print LIKE gxxlt_p OCCURS 0 WITH HEADER LINE.
*data:               keycol type i.
  FIELD-SYMBOLS:
  <comp_wa> TYPE abap_compdescr,
  tempfile = file_name.
  REFRESH header.
  CLEAR header.
  descr_ref ?= cl_abap_typedescr=>describe_by_data( i_tab ).
  DESCRIBE TABLE descr_ref->components LINES nlines.
  nlines = nlines + 1.
  LOOP AT descr_ref->components ASSIGNING <comp_wa>.
    IF sy-tabix = nlines.
      EXIT.
    ELSE.
      header-col_no = sy-tabix.
      header-col_name = <comp_wa>-name.
      APPEND header.
    ENDIF.
  ENDLOOP.
  CALL FUNCTION 'XXL_SIMPLE_API'
  EXPORTING
    filename = tempfile
N_KEY_COLS = keycol
  TABLES
   col_text = header[]
I appreciate your help. Thanks

Hi,
It's better to use another FM 'SAP_CONVERT_TO_XLS_FORMAT'
  call function 'SAP_CONVERT_TO_XLS_FORMAT'
             exporting
              I_FIELD_SEPERATOR = seper
              I_LINE_HEADER = 'X'
                 I_FILENAME = P_FILE
              tables
                  I_TAB_SAP_DATA = itab
              exceptions
                  CONVERSION_FAILED = 1.
