如何在RichTextColumns中垂直放置两个RichTextBlock(Overflow)

Question

如前所述，我想一个接一个地垂直放置两个RichTextBlocks。我的目的是手动编写第一个RichTextBlock的段落，我希望第二个RichTextBlock (其内容以编程方式给出)紧跟在第一个之后开始，并且我希望发生这种情况，以便第二个RichTextBlock将垂直溢出到下一列。

下面的代码片段只是为了让你能看到我正在使用的对象，没有任何逻辑意义。

<ScrollViewer 
        Grid.Column="1"
        Grid.Row="1" 
        Grid.RowSpan="2"
        HorizontalScrollMode="Auto"
        HorizontalScrollBarVisibility="Auto"
        VerticalScrollMode="Disabled"
        VerticalScrollBarVisibility="Disabled"
        Padding="20">

            <RichTextBlock>
                <Paragraph><Run></Run></Paragraph>
            <RichTextBlock />

            <common:RichTextColumns>
                <common:RichTextColumns.ColumnTemplate>
                    <DataTemplate>
                        <RichTextBlockOverflow Margin="80,0,0,0" Width="560">
                            <RichTextBlockOverflow.RenderTransform>
                                <TranslateTransform X="-1" Y="4"/>
                            </RichTextBlockOverflow.RenderTransform>
                        </RichTextBlockOverflow>
                    </DataTemplate>
                </common:RichTextColumns.ColumnTemplate>
                <RichTextBlock
                             htmlToXaml:Properties.Html="{Binding HtmlText}"
                             Name="RichTextBlockMy"
                             Margin="10,0,0,0"
                             Style="{StaticResource ItemRichTextStyle}"
                             Width="560"/>
            </common:RichTextColumns>
    </ScrollViewer>

我想这就是你想要的。

XAML

<ScrollViewer 
    HorizontalScrollMode="Auto"
    HorizontalScrollBarVisibility="Auto"
    VerticalScrollMode="Disabled"
    VerticalScrollBarVisibility="Disabled"
    Padding="20">
    <StackPanel Orientation="Horizontal">

        <RichTextBlock>
            <Paragraph>
                <Run Text="This is fixed RichTextBlock, after this it's RichTextBlock with RichTextColumns" FontSize="20"/>
                <LineBreak />
                <Run Text="{Binding FirstRtbText}" />
                <LineBreak />
                <Run Text="End of fixed RichTextBlock" FontSize="20" />
            </Paragraph>
            </RichTextBlock>

            <common:RichTextColumns>
            <common:RichTextColumns.ColumnTemplate>
                <DataTemplate>
                    <RichTextBlockOverflow Margin="80,0,0,0" Width="560">
                        <RichTextBlockOverflow.RenderTransform>
                            <TranslateTransform X="-1" Y="4"/>
                        </RichTextBlockOverflow.RenderTransform>
                    </RichTextBlockOverflow>
                </DataTemplate>
            </common:RichTextColumns.ColumnTemplate>
            <RichTextBlock 
                     common:Properties.Html="{Binding HtmlText}"
                     Name="RichTextBlockMy"
                     Margin="10,0,0,0"
                     Style="{StaticResource ItemRichTextStyle}"
                     Width="560"/>
        </common:RichTextColumns>
    </StackPanel>
</ScrollViewer>

C#

    public string HtmlText { get; set; }
    public string FirstRtbText { get; set; }
    public MainPage()
    {
        this.InitializeComponent();
        FirstRtbText = @"<h1>Header One</h1>
