yes strangely it gets displayed correctly if sortin is disabled....

row=table->rowCount();
table->insertRow(table->rowCount());
QTableWidgetItem *fir = new QTableWidgetItem();
QTableWidgetItem *sec = new QTableWidgetItem();
fir->setText(QString::number(a));
sec->setText(QString::number(b,16));
table->setItem(row, 0, fir);
table->setItem(row, 1, sec);
row++;
table->setSortingEnabled(true);
