如何删除所有列?谢谢。
最佳答案
//JTable variable name is jTable1_info....
model_info=(DefaultTableModel)jTable1_info.getModel();
//Clear all the column name on jtable jpanel-4
model_info.setColumnCount(0);
在此示例上的代码之前
//import the DefaultTableModel
import javax.swing.table.DefaultTableModel;
public final class homepage extends javax.swing.JFrame implements ActionListener
{
DefaultTableModel model_info;
public homepage() throws InterruptedException
{
initComponents();
create_column();//call method create jtable column names
}
}
private void create_column()
{
model_info=(DefaultTableModel)jTable1_info.getModel();
model_info.addColumn("Column_Name");
model_info.addColumn("Column_type");
model_info.addColumn("Column_size");
}
