QTableWidget - setCellWidget missing addition?

I am just trying to add widgets into my table widget and I am trying the code below but all the time I run the program, the first widget is added but the rest is not added. Can you please help me for this situation ? 

if(req.at(index).request.CodedValue.size() > 1 )
{
    int rowNumber = -1;
    for ( int paramNumber = 0 ; paramNumber < req.at(index).request.params.size(); paramNumber++)
    {

        if(req[index].request.params[paramNumber].semantic == "DATA")
        {
            rowNumber++;
            QComboBox* reqComboBox = new QComboBox();
            QLineEdit* tableReqLineEdit = new QLineEdit();

            for ( int codedCounter = 0; codedCounter < req.at(index).request.CodedValue.at(paramNumber).trams.size(); codedCounter++)
            {
                // you should look for the subfunctions and add according to them   
                reqComboBox->addItem((req[index].request.CodedValue[paramNumber].trams[codedCounter].valueName));
                QObject::connect(reqComboBox, SIGNAL(currentIndexChanged(int)), this, SLOT(on_tableCombobox_currentIndex());
            }
            ui.tableWidget->setCellWidget(rowNumber,1,reqComboBox);

        }
    }
}

Use qDebug in order to see how many times the for loop is executed. Probably it is executed only once:

#include <QDebug>
...
      rowNumber++;
      qDebug() << rowNumber;
...

Try the following:

for (int i=0; i<ui.tableWidget->rowCount(); i++)
{
      ui.tableWidget->setCellWidget(i,1,new QLineEdit);
}

How many line edits do you see?

Notice that you should use the setRowCount in order to set the number of rows of your table widget.
