如何创建 DefaultTableModel(TableModel 的一个实现)
java 8object oriented programmingprogramming更新于 2025/8/19 22:04:17
让我们创建 DefaultTableModel −
DefaultTableModel tableModel = new DefaultTableModel();
现在，将模型设置为 JTable −
JTable table = new JTable(tableModel);
添加列 −
tableModel.addColumn("Languages");
现在，我们将向表添加行 −
tableModel.insertRow(0, new Object[] { "CSS" });
tableModel.insertRow(0, new Object[] { "HTML5" });
以下是创建 DefaultTableModel 的示例 −
示例
package my;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.table.DefaultTableModel;
public class SwingDemo {
public static void main(String[] argv) throws Exception {
DefaultTableModel tableModel = new DefaultTableModel();
JTable table = new JTable(tableModel);
tableModel.addColumn("Languages");
tableModel.insertRow(0, new Object[] { "CSS" });
tableModel.insertRow(0, new Object[] { "HTML5" });
tableModel.insertRow(0, new Object[] { "JavaScript" });
tableModel.insertRow(0, new Object[] { "jQuery" });
tableModel.insertRow(0, new Object[] { "AngularJS" });
tableModel.insertRow(tableModel.getRowCount(), new Object[] { "ExpressJS" });
JFrame f = new JFrame();
f.setSize(550, 350);
f.add(new JScrollPane(table));
f.setVisible(true);
}
}
