QTextEdit printing margin problem

[eemxas]

As can be seen in the attached picture drawn in QTextEdit print from the table too much going on margins. And these gaps can not be changed.
I'm sorry for bad english, translation, google translate
code:
{
//QTextEdit add table:

QVector<QTextLength> columnWidth;
columnWidth.append (QTextLength(QTextLength::FixedLength, 15));
columnWidth.append (QTextLength(QTextLength::FixedLength, 20));
columnWidth.append (QTextLength(QTextLength::FixedLength, 100));
columnWidth.append (QTextLength(QTextLength::FixedLength, 80));
columnWidth.append (QTextLength(QTextLength::FixedLength, 70));
columnWidth.append (QTextLength(QTextLength::FixedLength, 80));
columnWidth.append (QTextLength(QTextLength::FixedLength, 70));
columnWidth.append (QTextLength(QTextLength::FixedLength, 30));
columnWidth.append (QTextLength(QTextLength::FixedLength, 30));
columnWidth.append (QTextLength(QTextLength::FixedLength, 30));
columnWidth.append (QTextLength(QTextLength::FixedLength, 30));
columnWidth.append (QTextLength(QTextLength::FixedLength, 40));
columnWidth.append (QTextLength(QTextLength::FixedLength, 30));
columnWidth.append (QTextLength(QTextLength::FixedLength, 50));
columnWidth.append (QTextLength(QTextLength::FixedLength, 50));
columnWidth.append (QTextLength(QTextLength::FixedLength, 50));
columnWidth.append (QTextLength(QTextLength::FixedLength, 50));
columnWidth.append (QTextLength(QTextLength::FixedLength, 150));
columnWidth.append (QTextLength(QTextLength::FixedLength, 40));

//QTextCursor cursor(ui->textBrowser->textCursor ());
QTextCursor cursor1(ui->textEdit->textCursor ());

cursor.movePosition(QTextCursor::Start);


QTextTableCellFormat cellFormat;
cellFormat.setLeftPadding(7);
cellFormat.setRightPadding(7);
QBrush blackBrush(Qt::SolidPattern);
QTextTableFormat tableFormat;
tableFormat.setAlignment(Qt::AlignLeft);
tableFormat.setBorderBrush(blackBrush);
tableFormat.setBorder(.5);
tableFormat.setCellSpacing(0);
tableFormat.setBorderStyle(QTextFrameFormat::Borde rStyle_Solid);
tableFormat.setWidth(QTextLength(QTextLength::Perc entageLength, 50));
tableFormat.setColumnWidthConstraints (columnWidth);

//QTextTable *table = cursor.insertTable (100,19, tableFormat);
QTextTable *table1 = cursor1.insertTable (100,19, tableFormat);
table->mergeCells (1,0,10,1);

QTextBlockFormat centerAlignment;
centerAlignment.setAlignment(Qt::AlignHCenter);
centerAlignment.setTextIndent (QTextOption::WordWrap);

cursor = table->cellAt(0, 0).firstCursorPosition();
cursor.setBlockFormat(centerAlignment);
cursor.insertText("Hello, this is my first post here!");
}

A great start would be reading the forum rules one of which is :
Use code tags for better reading, understanding, and viewing of code.

Thanks, that would take care of it.
