netbeans中表格使用1

1、  清空按钮

private voidjButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                        

        //清空数据

        DefaultTableModel dtm =(DefaultTableModel)jTable1.getModel();

         int row = jTable1.getSelectedRow();

         System.out.println(row);

         if(row==-1)

             row = 0;

         dtm.removeRow(row);

} 

2、  增加按钮

private voidjButton_AddActionPerformed(java.awt.event.ActionEvent evt) {                                           

       //增加数据

        String namestr =jTextField_Name.getText();

       String agestr =jTextField_Age.getText();

       String sexstr =jTextField_Sex.getText();

       String cardidstr =jTextField_CardID.getText();

       DefaultTableModel dtm =(DefaultTableModel)jTable1.getModel();

       Vector al = new Vector();

       al.add(namestr);

       al.add(sexstr);

       al.add(agestr);

       al.add(cardidstr);

       dtm.addRow(al);

    }
