</div></div>I have not use QML but I have a been working with QTableView a lot recently.<br>
<br>
I found that if I did not implement a QAbstractTableModel and update by<br>
calling the right methods the view will not update correctly. See<br>
beginInsertRows/beingRemoveRows and the dataChanged signal.<br>
<br>
You can see my code for the table model here:<br>
