C++, add/remove rows from a QTableWidget

Question

I'm creating a simple app with a table and an "Add row" button. Using Qt Creator I thought I can do something like this:

QObject::connect(ui->addRowButton, SIGNAL(clicked()),
                     ui->moneyTableWidget, SLOT(insertRow(1)));

But I can't. I'm really new to Qt and I could be wrong, but think the problem is that insertRow is not a SLOT method for QTableWidget...

How can I achieve the row insertion?
