WPF-設置datagridcell背景和水平對齊會弄亂背景

Question

通過多重綁定，我能夠設置特定細胞的背景。 但是，我想將單元格文本的horizo​​ntalalignment設置為正確，但這弄亂了應該拉伸整個背景的背景顏色 （不僅限於對齊的文本）：

這是最小的（可運行的）代碼

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>

我見過遇到類似問題的人，但是我不理解他試圖解釋的解決方案（ WPF：DataGridCell覆蓋行樣式的顏色 ）

-更新：設置Horizo​​ntalContentAlignment並不能完全解決問題，這會導致這種情況（右對齊以某種方式消失了）：

將您的TargetType和Setter屬性更改為以下修改后的代碼中的示例：

<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>
