C# 已移位列的WPF DataGrid边框

我完全不知道哪个属性是垂直单元格边界移动的原因。内容正确对齐，但边框似乎认为其对齐正确

XAML定义是：

<DataGrid x:Name="DG_ComparedSet" 
          AllowDrop="True"
          Background="AliceBlue"
          HorizontalAlignment="Stretch"
          AutoGenerateColumns="False" 
          PreviewDragEnter="File_DragEvent" 
          PreviewDragOver="File_DragEvent" 
          PreviewDrop="DG_ComparedSet_PreviewDrop">
    <DataGrid.ContextMenu>
        <ContextMenu>
            <MenuItem Header="Clear Comparison" Name="CXM_clearComparison" Click="CXM_clearComparison_Click" />
        </ContextMenu>
    </DataGrid.ContextMenu>
</DataGrid>

哪个属性丢失或设置不正确？

您的单元格对齐设置将中断列的渲染。在没有看到更多代码的情况下，我无法确定您的意图，但如果您希望单元格文本居中，则将内容居中，而不是单元格本身

Style cellStyle = new Style (typeof (DataGridCell));
cellStyle.Setters.Add (new Setter (DataGridCell.FontFamilyProperty, new FontFamily ("Consolas")));
//cellStyle.Setters.Add (new Setter (DataGridCell.HorizontalAlignmentProperty, HorizontalAlignment.Center));
//cellStyle.Setters.Add (new Setter (DataGridCell.VerticalAlignmentProperty, VerticalAlignment.Center));
cellStyle.Setters.Add (new Setter (TextBlock.TextAlignmentProperty, TextAlignment.Center));
cellStyle.Setters.Add (new Setter (DataGridCell.ForegroundProperty, Brushes.MediumSeaGreen));

当然，这是假设您的单元格只包含文本字符串

Style cellStyle = new Style (typeof (DataGridCell));
cellStyle.Setters.Add (new Setter (DataGridCell.FontFamilyProperty, new FontFamily ("Consolas")));
//cellStyle.Setters.Add (new Setter (DataGridCell.HorizontalAlignmentProperty, HorizontalAlignment.Center));
//cellStyle.Setters.Add (new Setter (DataGridCell.VerticalAlignmentProperty, VerticalAlignment.Center));
cellStyle.Setters.Add (new Setter (TextBlock.TextAlignmentProperty, TextAlignment.Center));
cellStyle.Setters.Add (new Setter (DataGridCell.ForegroundProperty, Brushes.MediumSeaGreen));
