Изменение цвета фона ячейки в JTable

Как изменить цвет отдельных ячеек на основе значения, которое они содержат?Изменение цвета фона ячейки в JTable

Вот что я основал на том, что нашел.

     int row, int column) { 
    // TODO Auto-generated method stub 
    return null; 
} 
}

Тогда Heres класс визуализатор, который должен изменить цвет фона

import java.awt.Color; 
import java.awt.Component; 
import javax.swing.JTable; 
import javax.swing.table.DefaultTableCellRenderer; 

public class MyRenderer extends DefaultTableCellRenderer 
{ 
public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) 
{ 
Component c = super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column); 

if (((int)table.getValueAt(row, column)) == 1) 
{ 
    System.out.println("hi"); 
} 
else 
{ 
    c.setBackground(table.getBackground()); 
} 
return c; 
} 

}

По умолчанию компонент рендеринга является JLabel. Ярлык не будет отображать цвет фона, если он не будет определен как непрозрачный. –

Чтобы лучше помочь, опубликуйте [MCVE] или [Short, Self Contained, Correct Example] (http://www.sscce.org/) , 1-й пример использования трещины: 'tableSeason1Drivers.getColumnModel(). GetColumn (0) .setPreferredWidth (21);' это не имеет никакого отношения к цветам фона. Второй пример - казалось бы, для таблицы нужны только две строки и два столбца. –

public static void main(String[] args) { 
    EventQueue.invokeLater(new Runnable() { 
     public void run() { 
      try { 
       DriversSeason1 window = new DriversSeason1(); 
       window.frameSeason1Drivers.setVisible(true); 
      } catch (Exception e) { 
       e.printStackTrace(); 
      } 
     } 
    }); 
    MyRenderer myRenderer = new MyRenderer(); 
    tableSeason1Drivers.setDefaultRenderer(Object.class, myRenderer); 
}

Основной метод работает на отдельном потоке, так что вы пытаетесь добавить визуализатор к столу ПЕРЕД DriversSeason1 класс создается.

Затем, когда код в разделе «Диспетчер событий» выполняется, создается класс DriverSeason1, и вы создаете новый JTable, чтобы все пользовательские средства визуализации были потеряны.

Решение прост. Добавьте рендеринга в таблицу при создании таблицы.

Кроме того, вы, класс DriversSeason1, не должны расширять JLabel и реализовывать TableCellRenderer. Избавьтесь от всего этого кода.

Наконец, при устранении этих проблем вы по-прежнему будете иметь ошибку в рендерере, который должен быть очевиден. Вы загружаете данные как объекты String, поэтому вы не можете ожидать создания объекта и целого. Вам нужно сделать сравнение строк в коде, а не целочисленное сравнение.

Ваш код имеет много плохого запаха, если вы не знаете, как сделать его лучше, я рекомендую вам прочитать некоторые книги, такие как Рефакторинг: Улучшение дизайна существующего кода и Эффективной Java.
В любом случае, я сделал это, пожалуйста, проверьте, действительно ли это то, что вы хотите.
