我是 WinUI 3 的新手，我正在做一个数据网格来显示产品列表，我想让数据网格列在总宽度不是完整数据网格宽度时填充数据网格，但如果总宽度则显示水平滚动列的宽度超过网格宽度。 我现在的网格 xaml 代码是这个：
<Grid x:Name="ContainerGrid">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<Grid x:Name="TableGrid" Grid.Column="0" HorizontalAlignment="Stretch" Margin="10,30,10,10" CornerRadius="5">
<controls:DataGrid x:Name="MainDataGrid" LoadingRow="ColorRow"
GridLinesVisibility="All" AutoGenerateColumns="False"
VerticalAlignment="Stretch" Width="Auto" MinWidth="{Binding ActualWidth, ElementName=TableGrid}"
HorizontalAlignment="Stretch" FrozenColumnCount="2"
Visibility="Visible">
<controls:DataGrid.Columns>
<controls:DataGridTemplateColumn Header="" Width="Auto">

如果我将 Width="*" 设置为最后一列，当总宽度超过数据网格宽度时，它将不会显示水平滚动，而是会将最后一列缩小为空
有人可以帮助我吗？
