ALV的颜色设置分为3种:行、列、单元格。
1.列颜色的设置
在 slis_t_fieldcat_alv-emphasize 中，写入需要的颜色代码。
Eg:
DATA: fc TYPE slis_t_fieldcat_alv WITH HEADER LINE.
fc-tabname = ‘ITAB‘.
fc-fieldname = ‘COL‘.
fc-emphasize = ‘C100‘.
append fc.
2.行颜色的设置
a.在要输出的 itab 中，加入 color 列，类型为C（4），记录需要的颜色代码。
b.设置 layout。alv_layout-info_fieldname = ‘COLOR‘.
Eg: DATA: BEGIN OF itab OCCURS 0.
INCLUDE STRUCTURE mara.
DATA: color(4) TYPE c.
DATA: END OF itab.
DATA: alv_layout TYPE slis_layout_alv.
itab-matnr = ‘123‘.
itab-color = ‘C200‘.
APPEND itab.
alv_layout-info_fieldname = ‘COLOR‘.
3.单元格颜色设置
a.在要输出的 itab 中，加入 color 列，类型为 slis_t_specialcol_alv，记录需要的颜色代码。
b.设置 layout。alv_layout-coltab_fieldname = ‘COLOR‘.
Eg: DATA: BEGIN OF itab OCCURS 0.
INCLUDE STRUCTURE mara.
DATA: color TYPE slis_t_specialcol_alv.
DATA: END OF itab.
DATA: color TYPE slis_t_specialcol_alv.
DATA: alv_layout TYPE slis_layout_alv.
color-color-col = ‘1‘.
color-color-int = ‘0‘.
color-color-inv = ‘0‘.
color-fieldname = ‘COL‘.
APPEND color.
itab-matnr = ‘123‘.
itab-color[] = color[].
APPEND itab.
alv_layout-coltab_fieldname = ‘COLOR‘.
以上是我对ALV GRID着色方法的一个总结，由于技术水平有限可能还存在一些遗漏，还望大家指出。
