C# -如何在同一列和/或行上创建具有独立拆分器的WPF接口？

<Window x:Class="WpfSplitterExample.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="WPF Splitter Example" Height="450" Width="800">
    <Grid>
        <!-- 定义行和列 -->
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto"/>
            <RowDefinition Height="*"/>
            <RowDefinition Height="Auto"/>
        </Grid.RowDefinitions>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="*"/>
            <ColumnDefinition Width="Auto"/>
            <ColumnDefinition Width="*"/>
        </Grid.ColumnDefinitions>

        <!-- 第一列 -->
        <TextBlock Grid.Row="0" Grid.Column="0" Text="Column 1, Row 1" Margin="10"/>
        <TextBox Grid.Row="1" Grid.Column="0" Margin="10"/>

        <!-- 拆分器 -->
        <Splitter Grid.RowSpan="3" Grid.Column="1" Width="5" HorizontalAlignment="Stretch" Background="Gray"/>

        <!-- 第三列 -->
        <TextBlock Grid.Row="0" Grid.Column="2" Text="Column 3, Row 1" Margin="10"/>
        <TextBox Grid.Row="1" Grid.Column="2" Margin="10"/>

        <!-- 行拆分器 -->
        <GridSplitter Grid.Row="1" Grid.ColumnSpan="3" Height="5" HorizontalAlignment="Stretch" VerticalAlignment="Center" Background="Gray"/>
    </Grid>
</Window>
