如何在WPF中定义TabItem标头模板

<Window x:Class="YourNamespace.YourWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="Your Window" Height="450" Width="800">
    <Window.Resources>
        <ResourceDictionary>
            <!-- Define TabItem Header Template Here -->
        </ResourceDictionary>
    </Window.Resources>
    
    <!-- Rest of the Window Content -->
</Window>

<DataTemplate x:Key="TabItemHeaderTemplate">
    <Grid>
        <!-- Customize TabItem Header Appearance Here -->
        <TextBlock Text="{Binding}" FontWeight="Bold" Foreground="White" />
    </Grid>
</DataTemplate>

<TabControl>
    <TabItem Header="Tab 1" HeaderTemplate="{StaticResource TabItemHeaderTemplate}">
        <!-- TabItem Content -->
    </TabItem>
    <TabItem Header="Tab 2" HeaderTemplate="{StaticResource TabItemHeaderTemplate}">
        <!-- TabItem Content -->
    </TabItem>
</TabControl>
