WPF中设置DataGrid的一些样式

<Window.Resources>  
    <Style TargetType="DataGrid">  
        <!--拖动改变单元格大小-->  
        <Setter Property="CanUserResizeColumns" Value="false"/>  
        <!--网格线颜色-->  
        <Setter Property="HorizontalGridLinesBrush">  
            <Setter.Value>  
                <SolidColorBrush Color="LightBlue"/>  
            </Setter.Value>  
        </Setter>  
        <Setter Property="VerticalGridLinesBrush">  
            <Setter.Value>  
                <SolidColorBrush Color="LightBlue"/>  
            </Setter.Value>  
        </Setter>  
    </Style>  
  
    <!--标题栏样式-->  
    <Style  TargetType="DataGridColumnHeader" >  
        <Setter Property="Width" Value="50"/>  
        <Setter Property="FontSize" Value="14" />  
        <Setter Property="Background" Value="lightBlue" />  
        <!--加粗-->  
        <Setter  Property="FontWeight"  Value="Bold"/>  
    </Style>  
  
    <!--行样式触发-->  
    <!--背景色改变必须先设置cellStyle 因为cellStyle会覆盖rowStyle样式-->  
    <Style  TargetType="DataGridRow">  
        <Style.Triggers>  
            <Trigger Property="IsSelected" Value="True">  
                <Setter Property="BorderBrush" Value="Red" />  
                <Setter Property="BorderThickness" Value="1" />  
            </Trigger>  
            <Trigger Property="IsMouseOver" Value="True">  
                <Setter Property="Background" Value="LightGray"/>  
            </Trigger>  
        </Style.Triggers>  
    </Style>  
      
    <!--单元格样式触发-->  
    <Style TargetType="DataGridCell">  
        <Style.Triggers>
