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);

}

3、修改按钮

private voidjButton2ActionPerformed(java.awt.event.ActionEvent evt) {

// 修改

int row = jTable1.getSelectedRow();

if(row>-1){

String namestr =jTextField_Name.getText();

String agestr = jTextField_Age.getText();

String sexstr =jTextField_Sex.getText();

String cardidstr =jTextField_CardID.getText();

jTable1.setValueAt(namestr, row,0);

jTable1.setValueAt(sexstr, row, 1);

jTable1.setValueAt(agestr, row, 2);

jTable1.setValueAt(cardidstr, row,3);

}

4、获取数据

private voidjTable1MouseClicked(java.awt.event.MouseEvent evt) {

//获取数据

int row = jTable1.getSelectedRow();

jTextField_Name.setText((String)jTable1.getValueAt(row, 0));

jTextField_Sex.setText((String)jTable1.getValueAt(row, 1));

jTextField_Age.setText((String)jTable1.getValueAt(row, 2));

jTextField_CardID.setText((String)jTable1.getValueAt(row,3));

}
