WPF-设置datagridcell背景和水平对齐会弄乱背景

Question

通过多重绑定，我能够设置特定细胞的背景。 但是，我想将单元格文本的horizo​​ntalalignment设置为正确，但这弄乱了应该拉伸整个背景的背景颜色 （不仅限于对齐的文本）：

这是最小的（可运行的）代码

public partial class MainWindow : Window
{
    public ObservableCollection<Test> MyData { get; set; }

    public MainWindow()
    {
        InitializeComponent();

        DataContext = this;
        MyData = Test.GetData();
    }
}

public class Test
{
    public string Title { get; set; }
    public string ColOne { get; set; }
    public string ColTwo { get; set; }

    public static ObservableCollection<Test> GetData()
    {
        return new ObservableCollection<Test>
        {
            new Test { Title = "HO", ColOne = "3.20", ColTwo = "5.85"},
            new Test { Title = "DOR", ColOne = "-3.33", ColTwo = "5.9"}
        };
    }
}

和XAML

<Window x:Class="ColorColumnAlignment.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <DataGrid ItemsSource="{Binding Path=MyData}">
            <DataGrid.Resources>
                <Style TargetType="DataGridCell">
                    <Style.Setters>
                        <Setter Property="HorizontalAlignment" Value="Right"></Setter>
                        <Setter Property="Background" Value="Chocolate"></Setter>
                    </Style.Setters>
                </Style>
            </DataGrid.Resources>
        </DataGrid>
    </Grid>
</Window>

我见过遇到类似问题的人，但是我不理解他试图解释的解决方案（ WPF：DataGridCell覆盖行样式的颜色 ）

-更新：设置Horizo​​ntalContentAlignment并不能完全解决问题，这会导致这种情况（右对齐以某种方式消失了）：

将您的TargetType和Setter属性更改为以下修改后的代码中的示例：

<Window x:Class="ColorColumnAlignment.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <DataGrid ItemsSource="{Binding Path=MyData}">
            <DataGrid.Resources>
                <Style TargetType="{x:Type TextBlock}">
                    <Style.Setters>
                        <Setter Property="TextAlignment" Value="Right" />
                        <Setter Property="Background" Value="Chocolate" />
                    </Style.Setters>
                </Style>
            </DataGrid.Resources>
        </DataGrid>
    </Grid>
</Window>
