具有别名列名称的Combobox DisplayMemberPath

Question

DisplayMemberPath可以与别名列名一起使用。

填充ComboBox的代码：

SQLiteConnection conn = MainWindow.DatabaseConnection();
try
{
     conn.Open();
}
catch (Exception ex)
{
     System.Windows.MessageBox.Show(ex.ToString());
}

string sql = @"SELECT CameraID, 
               Vendor.VendorName || ' ' || Camera.Model AS CameraName, 
               Camera.Active 
               FROM Camera 
               JOIN Vendor USING (VendorID) 
               ORDER BY CameraName";

SQLiteCommand com = new SQLiteCommand(sql, conn);
DataTable dataTable = new DataTable("Camera");
SQLiteDataAdapter ad = new SQLiteDataAdapter(sql, conn);
ad.Fill(dataTable);
_dataSet.Tables.Add(dataTable);
comboBoxTableEditMount.ItemsSource = dataTable.DefaultView;

XAML：

<ComboBox x:Name="comboBoxTableEditMount" 
Grid.Column="2" 
Grid.Row="8" 
DisplayMemberPath="CameraName"
SelectedValue="{Binding CameraID}"
SelectedValuePath="MountID"
Style="{DynamicResource ComboboxData}" 
Width="135" 
Margin="-80,0,0,0" />

ComboBox未列出任何商品。如果我将DisplayMemberPath更改为CameraID，则会显示数字。
