Xaml 如何使GridView的标题具有columnspan？

我有以下内容，其中白色矩形是GridViewItems，“能力”是标题

如何使标题位于所有列之上

简而言之，我的代码是：

<GridView Header="Abilities" Margin="0" SelectionMode="None" >
<GridViewItem></GridViewItem>
<GridViewItem></GridViewItem>
<GridViewItem></GridViewItem>
<GridViewItem></GridViewItem>
<GridViewItem></GridViewItem>
</GridView>

---

尝试将标题放在

网格视图之外

<TextBlock Text="Abilities"/>

<GridView Margin ="0" SelectionMode="None" />
    <GridViewItem></GridViewItem>
    <GridViewItem></GridViewItem>
    <GridViewItem></GridViewItem>
    <GridViewItem></GridViewItem>
    <GridViewItem></GridViewItem>
</GridView>

有两种选择：

<GridView HorizontalAlignment="Left" Width="400" Height="400" Header="Abilities">
    <GridView.ItemsPanel>
        <ItemsPanelTemplate>
            <VariableSizedWrapGrid Orientation="Horizontal" Width="400" />
        </ItemsPanelTemplate>
    </GridView.ItemsPanel>
    <GridViewItem/>
    <GridViewItem />
    <GridViewItem/>
    <GridViewItem />
    <GridViewItem />
    <GridViewItem />
</GridView>

或者，也

<Grid Width="400" Height="300">
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto" />
        <RowDefinition Height="*" />
    </Grid.RowDefinitions>
    <TextBlock Style="{StaticResource SubheaderTextStyle}" Text="Abilities" Margin="0 20" />
    <GridView Grid.Row="1">
        <GridViewItem />
        <GridViewItem />
        <GridViewItem />
    </GridView>
</Grid>
