如何在Java Swing中使用insertRow()向JTable添加新行

How to add a new row to JTable with insertRow() in Java Swing

让我们首先使用DefaulTabelMode创建一个表-

1 2	DefaultTableModel tableModel = new DefaultTableModel(); JTable table = new JTable(tableModel);

现在，在表格中添加一列-

1	tableModel.addColumn("Languages");

insertRow()方法现在将添加一行-

tableModel.insertRow(0, new Object[] {"CSS" });
tableModel.insertRow(0, new Object[] {"HTML5" });
tableModel.insertRow(0, new Object[] {"JavaScript" });
tableModel.insertRow(0, new Object[] {"jQuery" });

以下是向JTable添加新行的示例-

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" });
// adding a new row
tableModel.insertRow(tableModel.getRowCount(), new Object[] {"ExpressJS" });
JFrame f = new JFrame();
f.setSize(550, 350);
f.add(new JScrollPane(table));
f.setVisible(true);
}
}

这将产生以下输出-
