从QTableWidget移除项是否会删除内含对象？Qt对象删除触发排查

我使用Qt 5.15.2与C++开发项目，目前无法定位触发myCustomQObject对象删除的事件。下方的lambda函数会在myCustomQObject被删除时触发，进而发出communicationDeleted(serverName)信号，但不清楚该对象的删除触发源：

auto deletionConnection = connect(myCustomQObject, &QWidget::deleted, [myCustomQObject, this, serverName] (){
            communicationDeleted(serverName);
    });

创建对象及信号连接的代码 #

void myCustomTableWidget::addRow(const QString& serverName)
{
    myCustomQObject* newCustomQObject = new myCustomQObject(this);
    QWidget* newCellWidget = new QWidget();


    QHBoxLayout* rowLayout = new QHBoxLayout(newCellWidget);
    rowLayout->addWidget(myCustomQObject);

    newCellWidget->setLayout(rowLayout);

    m_ui->tableServers->insertRow(m_rowCount);
    m_ui->tableServers->setCellWidget(newCellWidget);

    auto deletionConnection = connect(myCustomQObject, &QWidget::deleted, [myCustomQObject, this, serverName] (){
            communicationDeleted(serverName);
    });

    m_->deletionConnections.pushBack(deletionConnection);
    ...
}

怀疑的删除触发点 #

我怀疑是myCustomTableWidget::deleteRow(qint32)槽函数导致对象删除：

void myCustomTableWidget::deleteRow(qint32 rowIndex)
{
    m_ui->tableServers->removeRow(rowIndex);
    m_rowCount--;
}

当删除表格中三个项时，该槽函数的断点会触发三次，但lambda函数是在后续流程中才执行。请问是否是移除表格行导致对象被删除？还是需要排查其他位置？
