ABAP学习（12）：Table Control显示

ABAP的Table Control

    Table Control是ABAP提供的内表显示控件，可以动态的显示操作内表数据。

示例1：自动创建Table Control

    1、创建项目Z_TEST_TC;

    2、创建屏幕100，右键选择creat->Screen;

 

     3、输入描述，然后点击layout;

 

    4、拖动1：手动建立Table Tontrol;拖动2：自动建立Table Control,这里我们先自动创建。

 

       5、弹出Table Control的自动创建步骤，选择continue;

 

     6、输入Table Control名，点击Continue;

 

     7、选择是使用ABAP的Dictonary中table的数据结构还是我们当前Program自定义的内表结构，这里我们选择使用Dictornary的数据结构，SPFLI;

 

     8、选择要显示的列，选择好后点击Continue;

 

     9、设置Table Control是否可输入，还是只输出显示；

 

     10、选择是否有Scroll等功能，选择Dictionary,不可选择；

 

     11、设置完成，显示效果，选择保存，激活；

屏幕100的Flow logic，自动生成代码：

在Controls:语句添加调用屏幕100就可以看到显示Table Control

"调用屏幕
CALL SCREEN 100.

设置工具栏，PF-STATUS

屏幕100，Flow logic解除MODUL STATUS_0100这行注释

MODULE STATUS_0100.

主程序逻辑：

"设置工具栏
MODULE STATUS_0100 OUTPUT.
  SET PF-STATUS 'STA_100'.
ENDMODULE.

设置用户操作功能

屏幕100，Flow logic解除USER_COMMAND_0100这行注释

MODULE USER_COMMAND_0100.

主程序逻辑：

MODULE USER_COMMAND_0100 INPUT.
  "点击退出
  CASE SY-UCOMM.
    WHEN 'EXIT'.
      LEAVE PROGRAM.
  ENDCASE.
ENDMODULE.                 " USER_COMMAND_0100  INPUT

示例2：选择Program自定义内表

    第7步选择Internal program table，设置Program中自定义的内表。这里我们就是使用主程序中的自定义内表t_spfli。

主程序逻辑：

"查询数据
SELECT * INTO CORRESPONDING FIELDS OF TABLE t_spfli FROM spfli.

"调用屏幕

示例3：手动创建Table Control

 拖选Table Control控件，输入Table Control名，这里TBC；Separators：设置分割线；Line Sel:设置行选择,单行或多行；Column Sel:设置列选择，单列或多列；这里直接选择拖动第1个，创建Table Control。

 

 拖动2，设置列栏位，拖动1设置列名；

屏幕100的Flow logic逻辑代码：

PROCESS BEFORE OUTPUT.
  MODULE STATUS_0100.
  LOOP WITH CONTROL TBL1.
    MODULE FILLTAB.
  ENDLOOP.

*
PROCESS AFTER INPUT.
  MODULE USER_COMMAND_0100.

  LOOP WITH CONTROL TBL1.
    MODULE UPDATETAB.
  ENDLOOP.

主程序逻辑代码：

DATA: OK_CODE TYPE SY-UCOMM.
"定义的表格控制器TBL1
CONTROLS: TBL1 TYPE TABLEVIEW USING SCREEN 0100.
"表格单元个控制
DATA:WA_COLS LIKE LINE OF TBL1-COLS.

"定义table显示的字段
DATA:BEGIN OF t_spfli OCCURS 0 ,
   carrid LIKE spfli-CARRID,
   cityfrom LIKE spfli-cityfrom,
   cityto LIKE spfli-cityto,
   fltype LIKE spfli-fltype,
END OF t_spfli.

"屏幕的字段Name就是 WA_SPFLI-内表结构名
DATA:wa_spfli LIKE LINE OF  t_spfli.
"手动创建没有垂直下拉条,需要NUMS参数设置行数
DATA:NUMS TYPE I.

"查询数据

"调用屏幕

MODULE STATUS_0100 OUTPUT.
  SET PF-STATUS 'STATUS_100'.
  "设置垂直下拉条

4.设置隐藏PF-STATUS按钮

          设置隐藏PF-STATUS,只需要在设置PF-STATUS时，设置需要隐藏的fcode内表。这里隐藏SHOW这个Function code。

 

 实例代码：

"设置status
DATA:lt_exfcode TYPE TABLE OF sy-ucomm.
"将要隐藏的Fcode加入内表
APPEND 'SHOW' TO lt_exfcode.

MODULE STATUS_0100 OUTPUT.
  "设置不显示Fcode
  SET PF-STATUS 'STATUS_100' EXCLUDING lt_exfcode.
  "设置垂直下拉条
  IF NUMS = 0.
    DESCRIBE TABLE t_spfli LINES NUMS.
    TBL1-LINES = NUMS.
  ENDIF.
ENDMODULE.
