推荐答案

这是摆脱中间文件的第一个答案的变体.

Here is a variation of the first answer that gets rid of the intermediate file.

QString strStream;
QTextStream out(&strStream);

const int rowCount = pPublic->tableView->model()->rowCount();
const int columnCount = pPublic->tableView->model()->columnCount();

out <<  "<html>
"
    "<head>
"
    "<meta Content="Text/html; charset=Windows-1251">
"
    <<  QString("<title>%1</title>
").arg(strTitle)
    <<  "</head>
"
    "<body bgcolor=#ffffff link=#5000A0>
"
    "<table border=1 cellspacing=0 cellpadding=2>
";

// headers
out << "<thead><tr bgcolor=#f0f0f0>";
for (int column = 0; column < columnCount; column++)
    if (!pPublic->tableView->isColumnHidden(column))
        out << QString("<th>%1</th>").arg(pPublic->tableView->model()->headerData(column, Qt::Horizontal).toString());
out << "</tr></thead>
";

// data table
for (int row = 0; row < rowCount; row++) {
    out << "<tr>";
    for (int column = 0; column < columnCount; column++) {
        if (!pPublic->tableView->isColumnHidden(column)) {
            QString data = pPublic->tableView->model()->data(pPublic->tableView->model()->index(row, column)).toString().simplified();
            out << QString("<td bkcolor=0>%1</td>").arg((!data.isEmpty()) ? data : QString("&nbsp;"));
        }
    }
    out << "</tr>
";
}
out <<  "</table>
"
    "</body>
"
    "</html>
";

QTextDocument *document = new QTextDocument();
document->setHtml(strStream);

QPrinter printer;

QPrintDialog *dialog = new QPrintDialog(&printer, NULL);
if (dialog->exec() == QDialog::Accepted) {
    document->print(&printer);
}

delete document;
