关于ALV表格颜色，这种需求在项目中会经常用到。
- 列颜色
列的颜色很简单，在构成ALV字段的FIELDCAT内表中有一个字段是EMPHASIZE，将一个char型4位的颜色代码分配到FIELDCAT内表这个字段即可。
LW_FCAT-EMPHASIZE = 'C710'. "设置字段的颜色 MODIFY IT_FIELDCAT FROM LW_FCAT TRANSPORTING EMPHASIZE WHERE FIELDNAME = 'ESLRY'.
- 行颜色
1. 在构成ALV数据的内表中，添加一个char型4位的字段（CLR），用来记录颜色代码
TABLES ZEMP_TEST.
TYPES: BEGIN OF TY_ZEMP.
INCLUDE STRUCTURE ZEMP_TEST.
TYPES: CLR TYPE CHAR4,"可以控制行颜色
END OF TY_ZEMP.
DATA: IT_ZEMP TYPE STANDARD TABLE OF TY_ZEMP,
IW_ZEMP TYPE TY_ZEMP.
2. 循环内表，设置颜色代码
LOOP AT IT_ZEMP INTO IW_ZEMP.
"员工编号为‘3的行，颜色为红色
IF IW_ZEMP-EMPID = '3'.
IW_ZEMP-CLR = 'C610'.
MODIFY IT_ZEMP FROM IW_ZEMP.
CLEAR IW_ZEMP.
ENDIF.
ENDLOOP.
3. LAYOUT结构中INFO_FIELDNAME的值指定为 CLR
IW_LAYOUT-INFO_FIELDNAME = 'CLR'. "行颜色代码的字段
- 单元格颜色
单元格颜色的设置与行颜色设计基本一致
1. 在构成ALV数据的内表中，添加一个内表 CellColor，用来记录颜色代码，需要设置颜色的字段名
TYPES: BEGIN OF TY_ZEMP.
INCLUDE STRUCTURE ZEMP_TEST.
TYPES: CLR TYPE CHAR4,
CELLCOLOR TYPE LVC_T_SCOL, "单元格颜色
END OF TY_ZEMP.
LOOP AT IT_ZEMP INTO IW_ZEMP.
"员工编号为‘3’的行，颜色为红色
IF IW_ZEMP-EMPID = '3'.
IW_ZEMP-CLR = 'C610'.
MODIFY IT_ZEMP FROM IW_ZEMP.
CLEAR IW_ZEMP.
ENDIF.
IF IW_ZEMP-EMPID = '2'.
IW_CELLCOLOR-FNAME = 'ENAME'.
"员工编号为‘2’的行的‘ENAME’字段颜色为 黄色
IW_CELLCOLOR-COLOR-COL = 3.
IW_CELLCOLOR-COLOR-INT = 1.
IW_CELLCOLOR-COLOR-INV = 0.
APPEND IW_CELLCOLOR TO IW_ZEMP-CELLCOLOR.
MODIFY IT_ZEMP FROM IW_ZEMP.
CLEAR IW_ZEMP.
ENDIF.
ENDLOOP.
3. LAYOUT结构中COLTAB_FIELDNAME的值指定为CELLCOLOR
IW_LAYOUT-COLTAB_FIELDNAME = 'CELLCOLOR'. "单元格颜色内表字段
最后在调用ALV函数时，设置layout，fieldcat参数
IS_LAYOUT = IW_LAYOUT
IT_FIELDCAT = IT_FIELDCAT
- ALV工具栏
可以自定义工具栏，或者添加标准ALV工具栏，然后去除一些不需要的功能，这样可以保留标准工具栏的功能
DATA:BEGIN OF TAB OCCURS 0,
FCODE LIKE RSMPE-FUNC,
END OF TAB.
TAB-FCODE = '&OL0'.APPEND TAB.
TAB-FCODE = '&OAD'.APPEND TAB.
TAB-FCODE = '&AVE'.APPEND TAB.
SET PF-STATUS 'STANDARD_FULLSCREEN' OF PROGRAM 'SAPLKKBL'
EXCLUDING TAB IMMEDIATELY.
- 求和
LW_FCAT-DO_SUM = 'X'. "立即求和，只有I,F,P类型的列可以求和
----------------------------------------------------------
运行效果如下：
在SE38环境下的程序名输入栏输入’DEMO*’后按F4，你可以查到SAP所有的DEMO示例程序，会学到很多ABAP功能的实现方法,
输入’BCALV*’后按F4，你可以查到很多ALV示例程序。
