qml TableView and group of columns

BePie

Is there an easy way to have grouped columns?
Let's say there is a item like that (item in c++ w/o proper interface and property setting, just for example):

class Item {
    QGeoCoordinate cord;
    QString name;
}

Now I want to have a TableView with headers like that:

name |       position        |
     |  lon  |  lat  |  alt  |
------------------------------
pos 1|  21.1 |  21.1 |  21.1 |
pos 2|  21.1 |  21.1 |  21.1 |
pos 3|  21.1 |  21.1 |  21.1 |

Is this doable (in a "clean" way) with TableView? I know I can create my own header and create roles for each coordinate part but I don't see how can I create this "group" of headers in a "clean" way (w/o hacking a lot).
