 <!--DataGridCellStyle-->
                <Style TargetType="{x:Type DataGridCell}">
                    <Setter Property="SnapsToDevicePixels" Value="true"/>
                    <Setter Property="BorderBrush" Value="Transparent"/>
                    <Setter Property="Foreground" Value="White"></Setter>
                    <Setter Property="BorderThickness" Value="1"/>
                    <Setter Property="Template">
                        <Setter.Value>
                            <ControlTemplate TargetType="{x:Type DataGridCell}">
                                <Border BorderBrush="{TemplateBinding BorderBrush}" HorizontalAlignment="Center" VerticalAlignment="Center" BorderThickness="{TemplateBinding BorderThickness}" Background="Transparent" SnapsToDevicePixels="True">
                                    <ContentPresenter  SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/>
                                </Border>
                            </ControlTemplate>
                        </Setter.Value>
                    </Setter>                </Style>重写单元格 模板，再写一个转换类 Converter ,绑定到Background上。
