Just got same problem and this is how I solved. I use QPoint that is a cleaner way to save a x-y value than a QString. Hope this helps.

classConstructor() {
    //some cool stuffs here
    tableVariationItemsSignalMapper = new QSignalMapper(this);
}

void ToolboxFrameClient::myRowAdder(QString price) {
    QLineEdit *lePrice;
    int index;
    //
    index = ui->table->rowCount();
    ui->table->insertRow(index);
    //
    lePrice = new QLineEdit(price);
    connect(lePrice, SIGNAL(editingFinished()), tableVariationItemsSignalMapper, SLOT(map()));
    tableVariationItemsSignalMapper->setMapping(lePrice, (QObject*)(new QPoint(0, index)));
    // final connector to various functions able to catch map
    connect(tableVariationItemsSignalMapper, SIGNAL(mapped(QObject*)),
             this, SLOT(on_tableVariationCellChanged(QObject*)));
}

void ToolboxFrameClient::on_tableVariationCellChanged(QObject* coords) {
    QPoint *cellPosition;
    //
    cellPosition = (QPoint*)coords;
}
