how could I make the listview header and the data align

 <StackLayout Orientation="Vertical">
        <StackLayout Padding="10,5,10,5">
            <SearchBar Text="{Binding keyValues,Mode=TwoWay}" Style="{StaticResource SearchBarStyle}" SearchCommand="{Binding SearchBarCommand}" />
        </StackLayout>
        <StackLayout Orientation="Horizontal" HorizontalOptions="FillAndExpand">
            <Label Text="车牌号" Style="{StaticResource HeaderStyle}" />
            <Label Text="发生时间" Style="{StaticResource HeaderStyle}" />
            <Label Text="栅栏名字" Style="{StaticResource HeaderStyle}" />
        </StackLayout>
        <ListView ItemsSource="{Binding ZhalanAlarmList,Mode=OneWay}" HasUnevenRows="True">
            <ListView.ItemTemplate>
                <DataTemplate>
                    <ViewCell>
                        <StackLayout Orientation="Horizontal" HorizontalOptions="FillAndExpand">
                            <Label Text="{Binding chepaino,Mode=OneWay}" Style="{StaticResource DetailStyle}" HorizontalOptions="Start" />
                            <Label Text="{Binding dthappen,Mode=OneWay}" Style="{StaticResource DetailStyle}" HorizontalOptions="CenterAndExpand" />
                            <Label Text="{Binding zhalanname,Mode=OneWay}" Style="{StaticResource DetailStyle}" HorizontalOptions="End" />
                        </StackLayout>
                    </ViewCell>
