QTableWIdget有控件时关于删除一行再添加一行时报错的问题（removeRow&insertRow）

今天做公司项目，想写个动态添加删除表格，表格里涉及到控件，我是先初始化好我需要的控件，然后动态添加到表格中，当我用removeRow删除一行后再添加的时候发现程序运行异常退出了，经过检查发现初始化的控件添加到表格里后通过removeRow删除并不会删除该控件被放在表格里，需要重新初始化`void DlgParameter::slot_add()
{
//m_pTabWidgt->setRowCount(10);
int m_row = m_pTabWidgt->rowCount();
qDebug()<<“m_row”<<m_row;
if(m_row<16)
{

    qDebug()<<"m_row++"<<m_row;
   //m_pTabWidgt->setRowCount(10);
   m_pTabWidgt->insertRow(m_row);

   m_pStarTimeEdit[m_row] = new QDateTimeEdit;           // 16个开始时间框
