qprint 和 QTextDocument 中的表格边距使用 html 作为输入

table margin in qprint and QTextDocument using html as input

本文关键字：html 输入 QTextDocument 表格 qprint      更新时间：2023-10-16

im 尝试使用 qprint 和带有 html 的 QTextDocument 打印 a4 格式的发票。但是我找不到任何解决方案来调整 HTML 表的左边距和右边距......

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;
