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。
