QT 修改QTableWidget表头

void NodeConfigDlg::initNodeTable()
{
    m_pNodeTable = new QTableWidget(this);
    QStringList headerString; 
 
    m_pNodeTable->setColumnCount(6);
    m_pNodeTable->setRowCount(2);
 
    QGridLayout *pGridLayOut = new QGridLayout(this);
    pGridLayOut->addWidget(m_pNodeTable, 0, 0);
 
    headerString<<"序号"<<"系统类型"<<"节点类型"<<"主机名"<<"A网"<<"B网";
    m_pNodeTable->setHorizontalHeaderLabels(headerString);
}

注意：修改表头的时候，必须要写在pGridLayOut的后面，如果写在GridLayOut的前面，则表头修改无效。
