问题：insertRow后给新增行各个单元格赋值时程序崩溃退出
代码如下：
/**
* 添加员工信息
* @brief AgencyManage::addAgency
*/
void AgencyManage::addAgency(){
AgencyManageSql agencySql;
QString recAccName = "";
QString recAccNo = "";
QString amount = "";
QString rem = "";
int row = ui->tableWidgetEmp->rowCount();//行数
int column = ui->tableWidgetEmp->columnCount();//列数
ui->tableWidgetEmp->insertRow(row);//插入新行
//插入数据库
agencySql.addAgencyInf(recAccName,recAccNo,amount,rem);
//获取序号（数据库中自增字段）
QString seqNo=agencySql.getSeqNo();
//定义各列组件
QTableWidgetItem *item1 = new QTableWidgetItem(seqNo);
item1->setTextAlignment(Qt::AlignCenter);//居中
QTableWidgetItem *item2 = new QTableWidgetItem(recAccName);
item2->setTextAlignment(Qt::AlignCenter);//居中
QTableWidgetItem *item3 = new QTableWidgetItem(recAccNo);
item3->setTextAlignment(Qt::AlignCenter);//居中
QTableWidgetItem *item4 = new QTableWidgetItem(amount);
item4->setTextAlignment(Qt::AlignCenter);//居中
QTableWidgetItem *item5 = new QTableWidgetItem(rem);
item5->setTextAlignment(Qt::AlignCenter);//居中
//最后一列添加删除按钮（扩展按钮）
QPushButtonEX *delBut = new QPushButtonEX();
delBut->setText(tr("删除"));
delBut->setFixedSize(12,20);
delBut->setMe(QString::number(row));//给按钮绑定行号
//删除员工信息
connect(delBut,SIGNAL(onClickMe(QString)),this,SLOT(delAgency(QString)));
QTableWidgetItem *checBox = new QTableWidgetItem();
checBox->setCheckState(Qt::Checked);
ui->tableWidgetEmp->setItem(row,0,checBox);
ui->tableWidgetEmp->setItem(row,1,item1);
ui->tableWidgetEmp->setItem(row,2,item2);
ui->tableWidgetEmp->setItem(row,3,item3);
ui->tableWidgetEmp->setItem(row,4,item4);
ui->tableWidgetEmp->setItem(row,5,item5);
ui->tableWidgetEmp->setCellWidget(row,6,delBut);
}
求高手帮忙看看！谢谢！
