如何在ALV中输出标题头

1、申明变量
DATA: GT_LIST_TOP_OF_PAGE TYPE SLIS_T_LISTHEADER.
 DATA:  GT_EVENTS   TYPE SLIS_T_EVENT.

2、定义供alv回调用Form
*---------------------------------------------------------------------*
*       FORM TOP_OF_PAGE                                              *
*---------------------------------------------------------------------*
*---------------------------------------------------------------------*
FORM TOP_OF_PAGE.

  CALL FUNCTION 'REUSE_ALV_COMMENTARY_WRITE'
       EXPORTING
*            i_logo             = 'HTMLCNTL_TESTHTM2_SAPLOGO'
            I_LOGO             = 'ENJOYSAP_LOGO'
            IT_LIST_COMMENTARY = GT_LIST_TOP_OF_PAGE.
ENDFORM.

3、定义填写输出ALV标题头输出内容的内表Form
FORM E04_COMMENT_BUILD USING E04_LT_TOP_OF_PAGE TYPE SLIS_T_LISTHEADER.
  DATA: LS_LINE TYPE SLIS_LISTHEADER.
*
* Listenüberschrift: Typ H
  CLEAR LS_LINE.
  LS_LINE-TYP  = 'H'.                   "显示为黑体，大号字
* LS_LINE-KEY:  not used for this type
  LS_LINE-INFO = TEXT-100.
  APPEND LS_LINE TO E04_LT_TOP_OF_PAGE.
* Kopfinfo: Typ S
  CLEAR LS_LINE.
  LS_LINE-TYP  = 'S'.                 "显示为标准字体大小
  LS_LINE-KEY  = TEXT-101.  "显示为标准字体大小，但是为黑体
  LS_LINE-INFO = TEXT-102. "显示为标准字体大小
  APPEND LS_LINE TO E04_LT_TOP_OF_PAGE.
  LS_LINE-KEY  = TEXT-103.
  LS_LINE-INFO = TEXT-104.
  APPEND LS_LINE TO E04_LT_TOP_OF_PAGE.
* Aktionsinfo: Typ A
  CLEAR LS_LINE.
  LS_LINE-TYP  = 'A'.                        "显示为斜体
* LS_LINE-KEY:  not used for this type
  LS_LINE-INFO = TEXT-105.
  APPEND LS_LINE TO  E04_LT_TOP_OF_PAGE.
ENDFORM. 

4、定义建立ALV事件内表FORM，将ALV事件内表的SLIS_EV_TOP_OF_PAGE事件处理函数名称替换成自定义的
FORM E03_EVENTTAB_BUILD USING E03_LT_EVENTS TYPE SLIS_T_EVENT.
  DATA: LS_EVENT TYPE SLIS_ALV_EVENT.
*
  CALL FUNCTION 'REUSE_ALV_EVENTS_GET'
       EXPORTING
            I_LIST_TYPE = 0
       IMPORTING
            ET_EVENTS   = E03_LT_EVENTS.
  READ TABLE E03_LT_EVENTS WITH KEY NAME =  SLIS_EV_TOP_OF_PAGE
                           INTO LS_EVENT.
  IF SY-SUBRC = 0.
    MOVE 'TOP_OF_PAGE'  TO LS_EVENT-FORM.
    APPEND LS_EVENT TO E03_LT_EVENTS.
  ENDIF.
ENDFORM.

5、调用函数
  PERFORM E03_EVENTTAB_BUILD USING GT_EVENTS[].
  PERFORM E04_COMMENT_BUILD  USING GT_LIST_TOP_OF_PAGE[].
  CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
       EXPORTING
           i_callback_program  =  sy-repid
            IT_FIELDCAT            = GT_FIELDCAT[]
            IT_SORT                   = GT_SORT[]
            IT_EVENTS               = GT_EVENTS[]
       TABLES
            T_OUTTAB                = GT_SFLIGHT.
