JTable разрывание при рендеринге

Я установил JTable и сделал его, чтобы он содержал 18 столбцов. Первоначально, когда это было 13 колонок, он прекрасно вписывался в JTable, и не было разрывов. Однако, как только я заставил его содержать 18 таблиц и отключить авторезист, когда я использую горизонтальную полосу прокрутки для прокрутки других столбцов, началось разрывание JTable, как показано на рисунке:JTable разрывание при рендеринге

Netbeans также начал давать мне много сообщений об ошибках, подобные этим:

Почему это так? Есть ли решение этой проблемы? Благодаря!

Так извините! Вот код, используемый для инициализации таблицы. Надеюсь, это будет полезно!

jp.setLayout(new BorderLayout()); 
    JTable jt = new JTable(data, column);// data and columns are just 2D and 1D String arrays each 
    JTableHeader th = jt.getTableHeader(); 
    th.setBackground(java.awt.Color.pink); 
    th.setEnabled(true); 
    jt.setTableHeader(th); 
    jt.setEnabled(false); 
    jp.add(jt, BorderLayout.CENTER); 
    JScrollPane scrollPane = new JScrollPane(jt, JScrollPane.VERTICAL_SCROLLBAR_ALWAYS, JScrollPane.HORIZONTAL_SCROLLBAR_AS_NEEDED); 
    jt.setAutoResizeMode(JTable.AUTO_RESIZE_OFF); 
    scrollPane.setEnabled(false); 
    jp.add(scrollPane, BorderLayout.CENTER);

В вашем коде явно что-то не так. Вероятно, ваши действия в стеке, вероятно, являются причиной вашей проблемы. Поместите некоторый код, который воспроизводит проблему. –

Добавлено в некоторый код! – Laughy

Я думаю, что вы указали больше столбцов, чем в вашем массиве данных.

Этот образец кода воспроизводит именно вашу проблему:

import javax.swing.JFrame; 
import javax.swing.JScrollPane; 
import javax.swing.JTable; 
import javax.swing.SwingUtilities; 

public class TestTable { 

    public JFrame f; 
    private JTable table; 

    public static void main(String[] args) { 
     SwingUtilities.invokeLater(new Runnable() { 

      @Override 
      public void run() { 
       new TestTable().initUI(); 
      } 
     }); 
    } 

    protected void initUI() { 
     String[][] data = new String[1][1]; 
     data[0] = new String[] { "hello" }; 
     String[] columns = new String[] { "Column-1", "Column-2" }; 
     table = new JTable(data, columns); 
     f = new JFrame(); 
     f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
     f.setSize(300, 300); 
     f.setLocationRelativeTo(null); 
     f.add(new JScrollPane(table)); 
     f.setVisible(true); 
    } 

}

Решение, конечно, чтобы число столбцов в данных совпадает с номером столбца, Вы заявляете. И вы должны убедиться, что каждая «строка» вашего массива данных инициализируется с правильным количеством «столбцов».

Например, вы могли бы это:

String[][] data = new String[1][18]; 
data[0] = new String[15]; // <-- This will cause some problems

Теперь, я бы рекомендовал использовать другую структуру данных, чем массивы, потому что это не очень гибким, и они, как правило, получить трудно поддерживать. Простое решение должны иметь некоторый класс «Model» и создать свой собственный TableModel как это:

import java.util.List; 
import java.util.Random; 
import java.util.Vector;

import javax.swing.JScrollPane;

Здесь все написано в одном классе, но, конечно, вы должны разделить их, чтобы правильно следовать MVC-шаблону.

Это решило мою проблему! Так глупо от меня ... Я объявил номер колонки короче, чем номер истинного столбца. – Laughy

Ответ в этой строке:

Исключение в потоке "АВТ-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException: 14 в

Это означает, что он знает, что он должен иметь больше столбцов , и он хотел рисовать следующий столбец, но не мог, потому что в базовой модели таблицы не было так много столбцов.

Предоставление таблицы 18 столбцов означает, что вам также необходимо обновить связанную модель таблицы. Оба должны синхронизировать работу таблицы.

Хмм, но модель таблицы, которую я использую, является табличной моделью по умолчанию ... Я не задал для нее никакой модели таблицы. Как обновить модель таблицы? Спасибо за вашу помощь! – Laughy

Я вижу, проблема уже решена - замечательный материал! – Ewald
