我的例子

QString data; 
m_printer.setPageSize(QPrinter::A4); 
m_printer.setOrientation(QPrinter::Landscape); 
QTextStream out(&m_strStream); 
const int rowCount = m_TableWidget->model()->rowCount(); 
const int columnCount = m_TableWidget->model()->columnCount(); 
out << "<html>\n" 
     "<head>\n" 
     "<meta Content=\"Text/html; charset=Windows-1251\">\n" 
    << QString("<title>%1</title>\n").arg("title") 
     << "</head>\n" 
      "<body bgcolor=#ffffff link=#5000A0>\n" 
      "<table border=1 cellspacing=0 cellpadding=2>\n"; 
out << "<thead><tr bgcolor=#f0f0f0>"; 
for (int column = 0; column < columnCount; column++) 
    if (!m_TableWidget->isColumnHidden(column)) 
     out << QString("<th>%1</th>").arg(m_TableWidget->model()->headerData(column, Qt::Horizontal).toString()); 
out << "</tr></thead>\n"; 
// data table 
out << "<tr>"; 
for (int column = 0; column < columnCount; column++) { 
    if(column%7 == 1) { 
     QString data = m_TableWidget->model()->data(m_TableWidget->model()->index(0, column)).toString().simplified(); 
     out << QString("<td colspan=7>%1</td>").arg((!data.isEmpty()) ? data : QString("&nbsp;")); 
    } else if(column == 0){ 
     QString data = m_TableWidget->model()->data(m_TableWidget->model()->index(0, column)).toString().simplified(); 
     out << QString("<td bkcolor=0>%1</td>").arg((!data.isEmpty()) ? data : QString("&nbsp;")); 
    } 
} 
out << "</tr>\n"; 
for (int row = 1; row < rowCount; row++) { 
    out << "<tr>"; 
    for (int column = 0; column < columnCount; column++) { 
     if(row==1 && column==1) 
     { data =m_ComboBox->currentText().simplified(); 
     } 
     if (!m_TableWidget->isColumnHidden(column)) { 
      data = m_TableWidget->model()->data(m_TableWidget->model()->index(row, column)).toString().simplified(); 
      out << QString("<td bkcolor=0>%1</td>").arg((!data.isEmpty()) ? data : QString("&nbsp;")); 
     } 
    } 
    out << "</tr>\n"; 
} 
out << "</table>\n" 
     "</body>\n" 
     "</html>\n"; 
m_document = new QTextDocument(); 
m_document->setHtml(m_strStream); 
m_dialog = new QPrintDialog(&m_printer, NULL); 
if (m_dialog->exec() == QDialog::Accepted) { 
    m_document->print(&m_printer); 
} 
delete m_document;
