如图所示：

同一行中有相同的字符串时，就高亮显示，如第二行中有相同字符串"中_张三"，就如图显示，可以是红色边框，也可以是红色背景，也可以是红色字体。
第四行中有相同字符串"汉_李四"如法炮制，在第四行第5列新填一个"汉_李四5"，那么新添加的也要高亮显示，谢谢！
初始代码：

PUBLIC oform1

oform1=Newobject("Form1")
oform1.Show
RETURN


DEFINE CLASS Form1 AS form
    Top = 0
    Left = 0
    Height = 256
    Width = 561
    DoCreate = .T.
    Caption = "Form1"
    Name = "Form1"

    ADD OBJECT Grid1 AS grid WITH ;
        DeleteMark = .F.,;
        Height = 200,;
        Left = 36,;
        RecordSource = "tt",;
        Top = 24,;
        Width = 504,;
        Name = "Grid1"

    PROCEDURE Load
        CLOSE ALL
        CREATE dbf  tt(A c(12),B c(12),C c(12),D c(12),E C(12),F c(12))
        INSERT INTO tt values("","","","","","")
        INSERT INTO tt values("中_张三1","","","","中_张三5","")
        INSERT INTO tt values("","","","","","")
        INSERT INTO tt values("","","","","","")
        INSERT INTO tt values("","汉_李四2","","汉_李四4","","")
        INSERT INTO tt values("","","","","","")
        GO top
    ENDPROC

ENDDEFINE

如何实现

你得先阐明啥叫相同，中_张三1 跟 中_张三5 显然不相同嘛

字符串中的汉字字符串相同，就视为相同，不考虑尾部的数字，谢谢！

能做到有条件选择某行某列单元格的颜色就OK
如：
行%列==1，红色
行%列==2，蓝色
行%列==3，绿色

如果一行中有两个 中_张三，还有两个 汉_李四，这该怎么显示？

都用红色显示即可，意思就是提醒有部分字符串相同，稍加注意而已，谢谢！

我确实办不到，谢谢！

thisform.grid1.COLUMNS(n).DYNAMICBACKCOLOR="IIF(条件,RGB(139,248,248),RGB(255,255,255))"
这是给列指定不同颜色的语句
关键是这其中的条件怎么设定？估计要加辅助字段了

要从源头解决问题，这样相对容易些。
