Wpf 通过TabControl.Resources的TabPanel的边距

如何通过TabControl设置TabPanel的边距。参考资料，我尝试了以下代码：

                    <TabControl.Resources>
                        <Style TargetType="TabPanel">
                            <Setter Property="Margin" Value="500,0,0,0" />
                        </Style>
                    </TabControl.Resources>
                </TabControl>

但由于某些原因，设置其宽度时不起作用：

                <TabControl.Resources>
                        <Style TargetType="TabPanel">
                            <Setter Property="Width" Value="500" />
                        </Style>
                    </TabControl.Resources>
                </TabControl>

目前我已经用模板设置了边距，但我想为一个单独的TabControl编辑边距

您需要在TabControl的模板中指定TabPanel的边距

比如：

非常感谢，这是一个有点代码的保证金！啊，我想TabPanel在设置边距时需要一些参考！是的，原因是因为您仍然希望维护默认模板，因此为了做到这一点，您还需要提供默认模板设置。我从以下位置获得默认模板：

    <Style  TargetType="{x:Type TabControl}">
        <Setter Property="OverridesDefaultStyle" Value="True" />
        <Setter Property="SnapsToDevicePixels" Value="True" />
        <Setter Property="Template">
        <Setter.Value>
          <ControlTemplate TargetType="{x:Type TabControl}">
            <Grid KeyboardNavigation.TabNavigation="Local">
              <Grid.RowDefinitions>
                <RowDefinition Height="Auto" />
                <RowDefinition Height="*" />
              </Grid.RowDefinitions>
              <VisualStateManager.VisualStateGroups>
                <VisualStateGroup x:Name="CommonStates">
                  <VisualState x:Name="Disabled">
                    <Storyboard>
                      <ColorAnimationUsingKeyFrames Storyboard.TargetName="Border"
                                                    Storyboard.TargetProperty="(Border.BorderBrush).
                        (SolidColorBrush.Color)">
                        <EasingColorKeyFrame KeyTime="0"
                                             Value="#FFAAAAAA" />
                      </ColorAnimationUsingKeyFrames>
                    </Storyboard>
                  </VisualState>

              </VisualStateManager.VisualStateGroups>
              <TabPanel x:Name="HeaderPanel"
