如何在 Java 中从 JTable 中删除选定的行?
awtjavaobject oriented programmingprogrammingswing
JTable 是 JComponent 类的子类，用于显示复杂的数据结构。JTable 组件可以遵循 模型视图控制器 (MVC) 设计模式，以 行和列 显示数据。JTable 可以生成 TableModelListener、TableColumnModelListener、ListSelectionListener、CellEditorListener 和 RowSorterListener 接口。我们可以使用 DefaultTableModel 类的 removeRow() 方法从 JTable 中删除 选定的行。
语法
public void removeRow(int row)
示例
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.table.*;
public class RemoveSelectedRowTest extends JFrame {
private JTable table;
private DefaultTableModel model;
private Object[][] data;
private String[] columnNames;
private JButton button;
public RemoveSelectedRowTest() {
setTitle("RemoveSelectedRow Test");
data = new Object[][] {{"101", "Ramesh"}, {"102", "Adithya"}, {"103", "Jai"}, {"104", "Sai"}};
columnNames = new String[] {"ID", "Name"};
model = new DefaultTableModel(data, columnNames);
table = new JTable(model);
table.setSelectionMode(javax.swing.ListSelectionModel.SINGLE_SELECTION);
button = new JButton("Remove");
button.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent ae) {
// check for selected row first if(table.getSelectedRow() != -1) {
// remove selected row from the model model.removeRow(table.getSelectedRow());
JOptionPane.showMessageDialog(null, "Selected row deleted successfully");
}
}
});
add(new JScrollPane(table), BorderLayout.CENTER);
add(button, BorderLayout.SOUTH);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setSize(400, 300);
setLocationRelativeTo(null);
setVisible(true);
}
public static void main(String args[]) {
new RemoveSelectedRowTest();
}
}
