关于SAP控件TABLE Control的用法,近期研究得到的几点如下:
1、使用向导创建table control时，提示“specify the work area of the table or a table with a header line”。检查系统定义，所绑定的内表已很明确地定义了内表的具有表头。后来摸索到，一个屏幕只允许使用向导创建一个table control，如果手工创建则不受限制。
2、 系统提示：Cannot currently edit include Repeat step?想了好久，在SAP论坛上发现老外也存在同样的问题待解决，http://forums.sdn.sap.com/thread.jspa?threadID=1195809
重复了几次，后来仔细想想，include是一个包，screen与程序绑定的，会不会是因为正在打开绑定的程序呢，于时在SE38中退出正在编辑的程序，重新操作则成功。
3、关于这个控件很好的学习资料。见http://blog.chinaunix.net/space.php?uid=150062&do=blog&id=2780070
4、table control配套按钮的设计。今年6月在使用时，为了设计配套按钮（如翻页、全选、全不选、新增、删除等）费了好多时间，还背了一段代码，而如果采用向导创建table Control，系统会自动帮我们设置，具体操作如下
一般情况下配置选择列。定义内表时，增加一列用于标记当前行是否被选中，该列的数据类型为 c，长度为 1， 在“line selectability”中勾选“line selection col”，并指定列名，同时可以指定是否允许选中 多行。如：
TABLES:SPFLI.
* 创建带有选择列的内表
TYPES:BEGIN OF SP1_TYPE,
ISSEL TYPE C,
CARRID LIKE SPFLI-CARRID,
CONNID LIKE SPFLI-CONNID,
COUNTRYFR LIKE SPFLI-COUNTRYFR,
CITYFROM LIKE SPFLI-CITYFROM,
AIRPFROM LIKE SPFLI-AIRPFROM,
COUNTRYTO LIKE SPFLI-COUNTRYTO,
CITYTO LIKE SPFLI-CITYTO,
AIRPTO LIKE SPFLI-AIRPTO,
END OF SP1_TYPE.
DATA:OK_CODE TYPE SY-UCOMM,
SP1 TYPE STANDARD TABLE OF SP1_TYPE WITH HEADER LINE,
SP2 TYPE STANDARD TABLE OF SP1_TYPE WITH HEADER LINE.
配置实现可编辑的table control。
1、在input/output attributes选项面板中，勾选“input control”。
2、在维护函数选项中，勾选“SCROLL”，“Insert/delete line”，“select/deselect all”选项，系统自动配套设计好相关操作按钮。
3、在屏幕被调用前，指定table control的长度。 如：
TBL2-LINES = 1000.
CALL SCREEN 100.
表格控制的行数固定为1000行，如果内表不足一千行，用空行代替,当从屏幕更新数据到内表时,系统会跳过为空的行,所以不用担心这样做会造成内表有很多空行. 一般情况下,当要求可编辑时,要求预留空行,否则,用TBL2_CHANGE_TC_ATTR控制.如果用户不允许空行的存在，则按以下方式
* 如果表格不允许空行的存在,则取消此处的注析,系统在显示前都会告知系统要显示的行数.
*&SPWIZARD: OUTPUT MODULE FOR TC ‘TBL2’. DO NOT CHANGE THIS LINE!
*&SPWIZARD: UPDATE LINES FOR EQUIVALENT SCROLLBAR
MODULE TBL2_CHANGE_TC_ATTR OUTPUT.
* DESCRIBE TABLE SP1 LINES TBL2-lines.
ENDMODULE.
自动录入功能增强。为了提高用户的友好性，提高用户的录入效率，有时候会根据用户录入的某些内容，自动带出其它相关的内容，只要监控相关列的值是否改变，如果有改变，即对其它相关列进行赋值。（table control中改变了界面的值后，只有按了enter键才会触发更改）。代码如：
流逻辑中监控字段的值是否改变
PROCESS AFTER INPUT.
*&SPWIZARD: PAI FLOW LOGIC FOR TABLECONTROL ‘TBL2’
LOOP AT SP1.
CHAIN.
FIELD SP1-ISSEL.
FIELD SP1-CARRID.
FIELD SP1-CONNID.
FIELD SP1-COUNTRYFR.
FIELD SP1-CITYFROM.
FIELD SP1-AIRPFROM.
FIELD SP1-COUNTRYTO.
FIELD SP1-CITYTO.
FIELD SP1-AIRPTO.
MODULE TBL2_MODIFY ON CHAIN-REQUEST.
ENDCHAIN.
ENDLOOP.
在程序中自动赋值：
* 当用户更改表格中的数据后,触发该事件
* 第一个SP1是内表,第二个SP1是表工作区,这个工作区和SP1表格控制绑定,在流逻辑中指定
* 在这里可以实现信息提示,根据之前输入的字段内容,确定后面的字段内容,
MODULE TBL2_MODIFY INPUT.
IF SP1-COUNTRYFR = ‘US’.
SP1-COUNTRYTO = ‘CHI’.
ENDIF.
IF SP1-COUNTRYFR = ‘CHI’.
SP1-COUNTRYTO = ‘US’.
ENDIF.
MODIFY SP1 FROM SP1 INDEX TBL2-CURRENT_LINE.
ENDMODULE.
