Question

我试图将formattedText1的输出放入一个新列。当前格式化的文本和formattedText1出现在一个连续列表中。我试过把+＆＃34; ＆＃34; +在formattedText和formattedText1之间，但是没有办法，我会很感激帮助

null, (formattedText) + (formattedText1), "Cashout Prices",

以下完整代码

package simpledialogbox;

import javax.swing.JOptionPane;
import java.io.IOException;
import java.util.logging.*;
import org.jsoup.*;
import org.jsoup.nodes.*;
import org.jsoup.select.*;

public class SimpleDialogBox {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        // TODO code application logic here
 try {
  String url = "http://bmreports.com/bsp/additional/soapfunctions.php?element=SYSPRICE&dT=2014-10-03";
  Document doc = Jsoup.connect(url).get();

  Elements SSPparagraphs;
  Elements SBPparagraphs; 
  SSPparagraphs = doc.select("SSP");
  SBPparagraphs = doc.select("SBP");


  String[] numbers = SSPparagraphs.text().toString().split(" ");
  String[] numbers1 = SBPparagraphs.text().toString().split(" ");

  String formattedText = new String("");
  String formattedText1 = new String("");

            for (int x = 0; x < numbers.length; x++)
            {
                formattedText += numbers[x] + "\n";
                  }

            for (int x = 0; x < numbers1.length; x++)
            {
               formattedText1 += numbers1[x] + "\n";
            }


            JOptionPane.showMessageDialog(
                null, (formattedText) + (formattedText1), "Cashout Prices", JOptionPane.PLAIN_MESSAGE);
            System.exit(0);
        }   




        catch (IOException ex) {
  Logger.getLogger(SimpleDialogBox.class.getName())
        .log(Level.SEVERE, null, ex);
   }
}


}

您可以使用HTML

（我修改了这个以说明你的两栏）

（注意：您在JFrame中使用JScrollPane可以获得更好的结果）

试试这个：

        String[] numbers = SSPparagraphs.text().toString().split(" ");
        String[] numbers1 = SBPparagraphs.text().toString().split(" ");

        //generate table and column heads
        String formattedText = new String("<html><table><tbody>");
        formattedText += "<tr><th>SSP</th><th>SBP</th></tr>";

        //populate table with data in two columns
        //will account for differing amounts of data between SBP and SSP
        int x = 0;
        while (x < numbers.length || x < numbers1.length)
        {
            formattedText += "<tr><td>";

            if (x < numbers.length)
            {
                formattedText += numbers[x];
            }
            else
            {
                formattedText += " ";
            }

            formattedText += "</td><td>";

            if (x < numbers1.length)
            {
                formattedText += numbers1[x];
            }
            else
            {
                formattedText += " ";
            }

            formattedText += "</td></tr>";

            x++;
        }

        formattedText += "<tbody></table>";
