[REUSE_ALV_GRID_DISPLAY]如何指定单元格颜色

下面简单介绍一下使用REUSE_ALV_GRID_DISPLAY函数时，如何设定单元格颜色，方法比较简单，直接上代码：

REPORT ztest_cell_color_grid_alv.
TYPE-POOLS: slis.
DATA: BEGIN OF git_flight OCCURS 0,
        carrid   LIKE sflight-carrid,
        connid   LIKE sflight-connid,
        fldate   LIKE sflight-fldate,
        seatsmax LIKE sflight-seatsmax,
        seatsocc LIKE sflight-seatsocc,
        color    TYPE lvc_t_scol,  "保存颜色的字段
      END OF git_flight.
DATA: git_fieldcat TYPE  slis_t_fieldcat_alv,
      gwa_layout   TYPE  slis_layout_alv.
DATA: gwa_col    TYPE lvc_s_scol,
      git_coltab TYPE lvc_t_scol,
      gwa_color  TYPE lvc_s_colo.
CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'
  EXPORTING
    i_program_name         = sy-repid
    i_internal_tabname     = 'GIT_FLIGHT'
    i_inclname             = sy-repid
  CHANGING
    ct_fieldcat            = git_fieldcat
  EXCEPTIONS
    inconsistent_interface = 1
    program_error          = 2.

SELECT carrid
       connid
       fldate
       seatsmax
       seatsocc
FROM sflight
INTO CORRESPONDING FIELDS OF TABLE git_flight
UP TO 20 ROWS.

* 设定颜色
gwa_color-col = '5'.
gwa_color-int = '0'.
gwa_color-inv = '0'.
LOOP AT git_flight.
* 指定第一行 SEATSOCC列单元格颜色
  IF sy-tabix = 1.
    gwa_col-fname = 'SEATSOCC'.
    gwa_col-color = gwa_color.
    APPEND gwa_col TO git_coltab.
    CLEAR gwa_col.
    git_flight-color = git_coltab.
    MODIFY  git_flight.
  ENDIF.
ENDLOOP.
gwa_layout-coltab_fieldname = 'COLOR'.
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
  EXPORTING
    i_callback_program = sy-repid
    is_layout          = gwa_layout
    it_fieldcat        = git_fieldcat
  TABLES
    t_outtab           = git_flight
  EXCEPTIONS
    program_error      = 1.

测试结果：

第一行的最后一列单元格颜色变为浅绿色。

以上。
