如何在不使用HTMLDocument的情况下在JTextPane中的两列中显示文本？

Question

我正在使用JTextPane，并希望仅在一部分内容中显示两列中的文本。我不能使用HTML，因为我必须在UI上显示一个图标（我从外部API获取javax.swing.Icon的实例，然后使用StyleConstants.setIcon添加它。）

我需要一个像this这样的布局，但使用的是DefaultStyledDocument。这可以实现吗？如果是这样我该怎么办？

以下是我的代码。我想和Paragraph2和Paragraph3并排。

import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import java.awt.Insets;
import java.awt.image.BufferedImage;
import java.net.URL;

import javax.imageio.ImageIO;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTextPane;
import javax.swing.text.DefaultStyledDocument;
import javax.swing.text.Document;
import javax.swing.text.SimpleAttributeSet;
import javax.swing.text.Style;
import javax.swing.text.StyleConstants;

public class Test
{
  public static void main(String[] args)
  {

    try
    {
      JFrame f = new JFrame("Test");
      f.getContentPane().setLayout(new GridBagLayout());
      JTextPane pane = new JTextPane();

      URL url = new URL(
          "http://files.softicons.com/download/toolbar-icons/fatcow-hosting-icons-by-fatcow/png/32/status_online.png");
      BufferedImage img = ImageIO.read(url);

      ImageIcon icon = new ImageIcon(img);

      Document document = pane.getDocument();
      Style style = ((DefaultStyledDocument) document).addStyle("StyleName", null);
      StyleConstants.setIcon(style, icon);
      document.insertString(document.getLength(), "ignored text", style);

      document.insertString(document.getLength(),
          "\n\nParagraph 1. Lorem Ipsum is simply dummy text of the printing and typesetting industry. "
              + "Lorem Ipsum has been the industry's standard dummy text ever since the 1500s,"
              + " when an unknown printer took a galley of type and scrambled it to make a type specimen book."
              + " It has survived not only five centuries, but also the leap into electronic typesetting",
          new SimpleAttributeSet());

      document.insertString(document.getLength(),
          "\n\nParagraph 2. Lorem Ipsum is simply dummy text of the printing and typesetting industry. "
              + "Lorem Ipsum has been the industry's standard dummy text ever since the 1500s,"
              + " when an unknown printer took a galley of type and scrambled it to make a type specimen book."
              + " It has survived not only five centuries, but also the leap into electronic typesetting",
          new SimpleAttributeSet());

      document.insertString(document.getLength(),
          "\n\nParagraph 3. Lorem Ipsum is simply dummy text of the printing and typesetting industry. "
              + "Lorem Ipsum has been the industry's standard dummy text ever since the 1500s,"
              + " when an unknown printer took a galley of type and scrambled it to make a type specimen book."
              + " It has survived not only five centuries, but also the leap into electronic typesetting",
          new SimpleAttributeSet());

      JScrollPane jScrollPane = new JScrollPane(pane);
      jScrollPane.setHorizontalScrollBarPolicy(JScrollPane.HORIZONTAL_SCROLLBAR_NEVER);

      f.getContentPane().add(
          jScrollPane,
          new GridBagConstraints(0, 0, 1, 1, 1, 1, GridBagConstraints.NORTHWEST, GridBagConstraints.BOTH, new Insets(0,
              0, 0, 0), 0, 0));
      f.setSize(500, 400);
      f.setVisible(true);
    }
    catch (Exception e)
    {
      throw new RuntimeException(e);
    }
  }
}
