Qt 4.7 export html document to pdf: strange

[giusepped]

I just moved to Qt 4.7. Compilation is a charm but when I use the export to pdf document of an html content, results are different with respect to previous version.
The code (that I did not change)


medie = " <table width=680><tbody><tr bgcolor=\"lightGray\" ><td colspan=3 >"+ QObject::tr("Valori medi mensili") +"</td></tr>";
medie +="<tr><td colspan=3>";
medie +="<table width=100% border=1 cellspacing=0 cellpadding=3 ><tr><td></td>";
medie += "<td>" + QObject::tr("Energia[")+unitEnergy+"]" + "</td>";
medie += "<td>" + QObject::tr("Fattore Ombre[%]") + "</td>";
medie += "<td>" + QObject::tr("Perdite termiche[%]") + "</td>";
medie += "<td>" + QObject::tr("Altre perdite[%]") + "</td>";
medie += "<td>" + QObject::tr("Temp. medie[^o]") + "</td>";
medie += "<td>" + QObject::tr("Vento medio[m/s]") + "</td>";
medie += "</tr>";

for(int i=0;i<12;i++) {
medie += "<tr>";
medie += "<td>" + MyMath::months(i+1) + "</td>";

if (Eset)
medie += "<td>" + QString("%L1").arg(E[i],0,'f',2) + "</td>";
else
medie += "<td>" + QString("%L1").arg(0) + "</td>";


medie += "<td>" + QString("%L1").arg((opt.shadows.at(i))*100,0,'f',2) + "</td>";


medie += "<td>" +QString("%L1").arg((1-
opt.thermalLosses.at(i))*100,0,'f',2) +"</td>";

medie += "<td>" + QString("%L1").arg((opt.otherLoss.at(i))*100,0,'f',2) +"</td>";


medie += "<td>" + QString("%L1").arg(opt.temperatures.at(i),0,'f',2) +"</td>";

medie += "<td>" +QString("%L1").arg(opt.wind.at(i),0,'f',2) + "</td>";

medie += "</tr>";
}
medie += "</table>";

medie += "</td></tr></tbody></table>";

And I print on a qprinter by using


m_cursor.insertHtml(medie);
m_document->drawContents(&p,printer->paperRect());

But the result is a broken table:mad:
as attached in the picture.
Why?

Nobody interested in this bug?
Can someone reproduce the same result?

What is the actual HTML that is generated? The snippet you provide above shows generation of part of a table inside (I assume) an outer table cell.

[giusepped]

No. If you look carefully there are two tables, one inside the other.
If I put the output to a file and then open it with a web browser, the result is correct.
In previous version of Qt I never had such misprinting problem.

Nobody intrested? I also have the same problem in other similar tables...simple Chrome-readable tables.
:(

I cannot reproduce the result with either 4.6.3 or 4.7.0 on Linux. I substituted 0 for the actual figures and the month number in place of the month name, but otherwise used your code. I also used the print() method of QTextDocument with good results.
