1. 纵向斑马线效果：实现网格的奇数列和偶数列分别以不同的颜色显示,以区别相邻的数据列。
file://在DbGrid的DrawColumnCell事件中编写如下代码：
Case DataCol Mod 2 = 0 of
True: DbGrid1.Canvas.Brush.Color:= clBlue; file://偶数列用蓝色
False: DbGrid1.Canvas.Brush.Color:= clAqua; file://奇数列用浅绿色
End;
DbGrid1.Canvas.Pen.Mode:=pmMask;
DbGrid1.DefaultDrawColumnCell (Rect, DataCol, Column, State);
2. 纵向斑马线，同时以红色突出显示当前单元格效果：以突出显示当前选中的字段。
file://将上述代码修改为：
Case DataCol Mod 2 = 0 of
True: DbGrid1.Canvas.Brush.Color:= clBlue; file://偶数列用蓝色
False: DbGrid1.Canvas.Brush.Color:= clAqua; file://奇数列用浅绿色
End;
If ((State = [gdSelected]) or (State=[gdSelected,gdFocused])) then
If Not DbGrid1.SelectedRows.CurrentRowSelected then
DbGrid1.Canvas.Brush.Color:=clRed; file://当前选中单元格显示红色 DbGrid1.Canvas.Pen.Mode:=pmMask;
DbGrid1.DefaultDrawColumnCell (Rect, DataCol, Column, State);
上述两种方法突出了列的显示效果。
3．在数据网格中以红色突出显示当前选中的行。
设置DbGrid控件的Options属性中的dgRowSelect属性为真，Color属性为clAqua(背景色), 在DbGrid的DrawColumnCell事件中编写如下代码：
if ((State = [gdSelected]) or (State=[gdSelected,gdFocused])) then
DbGrid1.Canvas.Brush.color:=clRed; file://当前行以红色显示，其它行使用背景的浅绿色
DbGrid1.Canvas.pen.mode:=pmmask;
DbGrid1.DefaultDrawColumnCell (Rect, DataCol, Column, State);
4．行突显的斑马线效果：既突出当前行，又区分不同的列（字段）。
file://其它属性设置同3，将上述代码修改为：
if ((State = [gdSelected]) or (State=[gdSelected,gdFocused])) then
begin
Case DataCol Mod 2 = 0 of
True : DbGrid1.Canvas.Brush.color:=clRed; file://当前选中行的偶数列显示红色
False: DbGrid1.Canvas.Brush.color:=clblue; file://当前选中行的奇数列显示蓝色
end;
DbGrid1.Canvas.pen.mode:=pmmask;
DbGrid1.DefaultDrawColumnCell (Rect, DataCol, Column, State);
end;
5．横向斑马线， 同时以红色突显当前行效果。
file://其它属性设置同3，将上述代码修改为：
Case Table1.RecNo mod 2 = 0 of file://根据数据集的记录号进行判断
True : DbGrid1.Canvas.Brush.color:=clAqua; file://偶数行用浅绿色显示
False: DbGrid1.Canvas.Brush.color:=clblue; file://奇数行用蓝色表示
end;
if ((State = [gdSelected]) or (State=[gdSelected,gdFocused])) then file://选中行用红色显示
DbGrid1.Canvas.Brush.color:=clRed;
DbGrid1.Canvas.pen.mode:=pmMask;
DbGrid1.DefaultDrawColumnCell (Rect, DataCol, Column, State);
6．双向斑马线效果：即行间用不同色区分，同时，选中行以纵向斑马线效果区分不同的列。
file://其它属性设置同3，将上述代码修改为：
Case Table1.RecNo mod 2 = 0 of file://根据数据集的记录号进行判断
True : DbGrid1.Canvas.Brush.color:=clAqua; file://偶数行用浅绿色显示
False: DbGrid1.Canvas.Brush.color:= clblue; file://奇数行用蓝色表示
end;
If ((State = [gdSelected]) or (State=[gdSelected,gdFocused])) then
Case DataCol mod 2 = 0 of
True : DbGrid1.Canvas.Brush.color:=clRed; file://当前选中行的偶数列用红色
False: DbGrid1.Canvas.Brush.color:= clGreen; file://当前选中行的奇数列用绿色表示
end;
DbGrid1.Canvas.pen.mode:=pmMask;
DbGrid1.DefaultDrawColumnCell (Rect, DataCol, Column, State);
