QT 修改QTableWidget表頭

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<<"序號"<<"系統類型"<<"節點類型"<<"主機名"<<"A網"<<"B網";
    m_pNodeTable->setHorizontalHeaderLabels(headerString);
}

注意：修改表頭的時候，必須要寫在pGridLayOut的後面，如果寫在GridLayOut的前面，則表頭修改無效。
