After resetting the model, the header cannot be set again.

QStringList strlist = TableHeaderSetup();

	//m_pChart->setTitle(m_pStcInfo->strMethodName);
	//m_pChart->removeAllSeries();

	// [DataTable]
	if (!m_pDataModel)
		m_pDataModel = new usrStandardTableModel();
	else
	{
	
m_pDataModel->beginResetModel();
m_pDataModel->clear();
m_pDataModel->endResetModel();

}
	this->ui.tableWidget->setModel(m_pDataModel);
	m_pDataModel->setHorizontalHeaderLabels(strlist);

	// [HeaderTable] 
	if (!m_pHeaderModel)
		m_pHeaderModel = new usrStandardTableModel();
	else
		m_pDataModel->InitData();			// 여기서 reset model을 함
	m_pHeaderModel->setHorizontalHeaderItem(0, new QStandardItem(strlist.at((int)CollectEnums::SingleTableHeaderItems::Index)));
	this->ui.tableWidget->InitFrozenTableview(m_pHeaderModel, (float)1.5, true);

After resetting the model, the header cannot be set again.

@IknowQT
Very unclear what you are saying is happening here. If you reset the m_pDataModel maybe you need to reset the m_pHeaderModel too?
