    connect(combobox, SIGNAL(currentIndexChanged(int)), SLOT(slot_comboboxIndexChanged(int)));

    void slot_comboboxIndexChanged(int index)
    {
    QComboBox senderComboBox = (QComboBox)sender();
    for (int i = 0; i < ui->tablWidget>rowCount(); i++) {
    QComboBox uiComboBox = (QComboBox)ui->tableWidget->cellWidget(i, 0);
    if (senderComboBox == uiCOmboBox){
    //得到senderComboBox的行号
    }
    }

    connect(combobox, SIGNAL(currentIndexChanged(int)), this, SIGNAL(OnCurrentIndexChanged(int)));

    connect(combobox, SIGNAL(currentIndexChanged(int)), this, SIGNAL(OnCurrentIndexChanged(int)));
    然后在函数中直接调用tablewidget的currentRow()即可。
