如图所示，我不想显示最后一行（最后一条红线）下的线在这个数据网格，但其他水平线显示正常，怎么做？
数据网格的行设置是针对所有行的，所以我不能只设置最后一行的行视觉样式。

您可以通过以下步骤来实现这一点：
1.将DataGrid的GridLinesVisibility属性设置为None。（隐藏所有水平和垂直网格线）
2.将DataGridTextColumn替换为DataGridTemplateColumn，并将Border Package 的单元格内容放入DataGridTemplateColumn的CellTemplate中
3.将Border的BorderThickness设置为"0,1,0,0"，将Margin设置为"-1"，将BorderBrush设置为您喜欢的任何颜色
下面是一个可能的基于原始代码的示例代码段：
