本文主要是介绍如何通过cl_dd_document来实现在ALV中输出标题头，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
样例代码:
REPORT ZTEST4.
TABLES : t001.
TYPE-POOLS: slis.
DATA : w_repid LIKE sy-repid.
TYPES : BEGIN OF ty_comp.
INCLUDE STRUCTURE t001.
TYPES : END OF ty_comp.
DATA: wa_layout TYPE slis_layout_alv.
DATA: it_fieldcat TYPE slis_t_fieldcat_alv,

DATA : it_comp TYPE TABLE OF ty_comp.
INITIALIZATION.
w_repid = sy-repid.
START-OF-SELECTION.
SELECT * FROM t001 INTO TABLE it_comp.
END-OF-SELECTION.
CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'
EXPORTING
i_program_name = w_repid
i_internal_tabname = 'IT_COMP'
I_STRUCTURE_NAME = 'T001'
i_inclname = w_repid
CHANGING
ct_fieldcat = it_fieldcat[]
EXCEPTIONS
inconsistent_interface = 1
program_error = 2
OTHERS = 3.
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
EXPORTING
i_callback_program = w_repid
i_callback_html_top_of_page = 'HTML_TOP_OF_PAGE'
is_layout = wa_layout
it_fieldcat = it_fieldcat
TABLES
t_outtab = it_comp
EXCEPTIONS
program_error = 1
OTHERS = 2.

*&---------------------------------------------------------------------*
FORM html_top_of_page USING document TYPE REF TO cl_dd_document.
DATA: text TYPE sdydo_text_element.
text = 'Company Code Data'.
CALL METHOD document->add_text
EXPORTING
text = text
sap_style = 'HEADING'.
CALL METHOD document->new_line.
CALL METHOD document->new_line.
text = 'User Name : '.
CALL METHOD document->add_text
EXPORTING
text = text

CALL METHOD document->add_gap
EXPORTING

CALL METHOD document->add_text
EXPORTING
text = text
sap_style = 'Key'.
CALL METHOD document->add_gap
EXPORTING
width = 10.

CALL METHOD document->add_text
EXPORTING
text = text

CALL METHOD document->new_line.
ENDFORM. "HTML_TOP_OF_PAGE
效果图如下:
