如何为WPF 4 DataGrid的列标题添加右键单击上下文菜单？

<DataGrid x:Name="dataGrid" AutoGenerateColumns="False" ItemsSource="{Binding DataList}">
    <DataGrid.Resources>
       <ContextMenu x:Key="ColumnHeaderContextMenu">
           <MenuItem Header="重命名" Command="{Binding ColumnRenameCommand}" />
           <MenuItem Header="排序" Command="{Binding ColumnSortCommand}" />
           <MenuItem Header="隐藏" Command="{Binding ColumnHideCommand}" />
        </ContextMenu>
    </DataGrid.Resources>
    <DataGrid.Columns>
        <DataGridTextColumn Header="ID" Binding="{Binding ID}" />
        <DataGridTextColumn Header="名称" Binding="{Binding Name}" />
        <DataGridTextColumn Header="描述" Binding="{Binding Description}" />
    </DataGrid.Columns>
</DataGrid>

public MainWindow()
{
    InitializeComponent();
    dataGrid.ColumnHeaderContextMenu = (ContextMenu)dataGrid.Resources["ColumnHeaderContextMenu"];
}

public class MainViewModel : INotifyPropertyChanged
{
    public ICommand ColumnRenameCommand { get; private set; }
    public ICommand ColumnSortCommand { get; private set; }
    public ICommand ColumnHideCommand { get; private set; }

    public MainViewModel()
    {
        ColumnRenameCommand = new RelayCommand(ColumnRename);
        ColumnSortCommand = new RelayCommand(ColumnSort);
        ColumnHideCommand = new RelayCommand(ColumnHide);
    }

    private void ColumnRename()
    {
        // 重命名列的逻辑
    }

    private void ColumnSort()
    {
        // 排序列的逻辑
    }

    private void ColumnHide()
    {
        // 隐藏列的逻辑
    }

    // 其他代码
}

private void ColumnRename()
{
    // 重命名列的逻辑
}

private void ColumnSort()
{
    // 排序列的逻辑
}

private void ColumnHide()
{
    // 隐藏列的逻辑
}
