QTableWidget usage example

1 Create Row Header

 QStringList cHeader;cHeader << "Number" << "Name" << "Date" ;m_tableWidget->setHorizontalHeaderLabels(cHeader);

After creation, it is found that the header cannot be displayed!

The number of lines created when 1 is constructed

 m_tableWidget = new QTableWidget(10,10,this);

2

 m_tableWidget->setRowCount(10);m_tableWidget->setColumnCount(3);
