wpf - 表格列宽和水平对齐方式

Question

我在整个互联网上进行了搜索，但找不到将表格列拉伸(stretch)到内容宽度以及如何将表格集中在屏幕中间的简单解决方案。它总是左对齐。我试过 <TableColumn width="Auto"> .它没有耍花招。唯一有用的是 <TableColumn width="200"> .如何使列拉伸(stretch)到内容宽度，以及如何将表格放在屏幕中间？或者，我应该只求助于网格选项吗？

这是我的 XAML:

    <!--</ScrollViewer>-->

</Grid>

<Window.Background>
    <LinearGradientBrush EndPoint="0.5,0" StartPoint="0.5,1">
        <GradientStop Color="Gray" Offset="0" />
        <GradientStop Color="White" Offset="1" />
    </LinearGradientBrush>
</Window.Background>

这是我得到的结果:

Answer 1

让表格居中对齐

<Table HorizontalAlignment="Centre" VerticalAlignment="Center">

& 使列宽尝试使用 * 而不是 Auto 或输入一些数字然后 * 如“2*”
