alv的颜色分为行的颜色、列的颜色和cell的颜色。
*------- 行的颜色 --------------------------------------------------------
* 需要在要显示的内表中添加一个字段放置颜色信息，比如color(4) type c .
itab-color = 'C700'.
*此外，还要根据采用的fm方式还是class方式设置一下显示颜色
*---fm方式：
data: ls_layout type slis_layout_alv.
ls_layout-info_fieldname = 'COLOR'.
call function 'REUSE_ALV_GRID_DISPLAY'
exporting
is_layout = ls_layout
it_fieldcat = lt_fieldcat
tables
t_outtab = itab.
*---class方式：
sla-info_fname = 'COLOR'.
call method go_grid->set_table_for_first_display
exporting
is_variant = gs_variant
i_save = 'A'
is_layout = sla
changing
it_outtab = itab[]
it_fieldcatalog = gt_fieldcat[]
exceptions
invalid_parameter_combination = 1
program_error = 2
too_many_lines = 3
others = 4.
*------- 列颜色 ---------------------------------------------------------
很简单,如：
data: it_fieldcat TYPE slis_t_fieldcat_alv.
it_fieldcat-EMPHASIZE = 'C500'.
*------- 单元格颜色 -------------------------------------------------------
1. 在输出内表中添加字段 cellcolor TYPE lvc_t_scol . 这是一个内表，用来存储单元格的颜色。
2. 在内表循环中给这个内表赋值，示例代码如下：
DATA wa_cellcolor TYPE lvc_s_scol. " 单元格颜色结构
wa_cellcolor-fname = 'TEXT_DECIMAL1'.
wa_cellcolor-color-col = '6'.
wa_cellcolor-color-int = '1'.
wa_cellcolor-color-inv = '0'.
APPEND wa_cellcolor TO gt_output-cellcolor.
3. 最关键的一点，在layout结构中设定颜色字段的名字，代码如下：
is_layout-coltab_fieldname = 'CELLCOLOR'. " 单元格颜色字段
总结：当同时设定了行颜色和列颜色后，行颜色会覆盖列颜色，有的时候用户不希望这种结果的出现，解决办法就是设定每行的单元格（当然不包括与设定列颜色的列相交叉的单元格）的颜色。
附录：ABAP颜色代码
ABAP中的颜色代码是由4位字都组成的 Cxyz
C：color的简写，颜色代码均以C开头
x：标准色代码，SAP中一共有7个标准色
y：反转颜色启用/关闭 1/0
z：增强颜色启用/关闭 1/0
标准色代码一览表:
------------------------------------
X 颜色 主要用处
------------------------------------
1 灰蓝色 抬头、标题栏
2 浅灰色 列表内容
3 黄色 汇总
4 蓝色 关键字
5 绿色 正确
6 红色 错误
7 橙色 控制
