title: C++, add/remove rows from a QTableWidget
body: <p>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:</p>
  
  <pre><code>QObject::connect(ui-&gt;addRowButton, SIGNAL(clicked()),
                       ui-&gt;moneyTableWidget, SLOT(insertRow(1)));
  </code></pre>
  
  <p>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...</p>
  
  <p>How can I achieve the row insertion?</p>
