如何将上下文菜单添加到wpf datagrid？

<ContextMenu x:Key="MyContextMenu">
    <MenuItem Header="编辑" Command="{Binding EditCommand}" />
    <MenuItem Header="删除" Command="{Binding DeleteCommand}" />
</ContextMenu>

<DataGrid>
    <DataGrid.Columns>
        <DataGridTextColumn Header="姓名" Binding="{Binding Name}">
            <DataGridTextColumn.CellStyle>
                <Style TargetType="DataGridCell">
                    <Setter Property="ContextMenu" Value="{StaticResource MyContextMenu}" />
                </Style>
            </DataGridTextColumn.CellStyle>
        </DataGridTextColumn>
        <!-- 其他列 -->
    </DataGrid.Columns>
</DataGrid>

public ICommand EditCommand { get; }
public ICommand DeleteCommand { get; }

public MyViewModel()
{
    EditCommand = new RelayCommand(Edit);
    DeleteCommand = new RelayCommand(Delete);
}

private void Edit()
{
    // 处理编辑操作
}

private void Delete()
{
    // 处理删除操作
}
