How to correctly change the row height of a TableView

Window {
    id: uninstallWindow
    width: 640
    height: 480

    property variant pluginData;

    TableView {
        id:_pluginTable
        anchors.right: parent.right
        anchors.rightMargin: 0
        anchors.left: parent.left
        anchors.leftMargin: 0
        anchors.bottom: parent.bottom
        anchors.bottomMargin: 43
        anchors.top: parent.top
        anchors.topMargin: 0
        model: pluginData

        itemDelegate: Text {
            text: modelData
            font.pixelSize: 24
        }

        TableViewColumn {
        
        }
    }
}

I change the font size of the items in the table because they were too small by default. This simply caused them to get clipped by the non-changing row size.

I've tried:

1. Setting a rowDelegate object (but this causes loss of all other styling info that is there by default like background, selection color, etc and I don't know how to specify it otherwise)

2. Setting a custom model object based on QAbstractListModel/QAbstractTableModel (for some reason only known to Qt, the "data" function was never ever called...)

3. Setting a custom item delegate (it seems that the height is no longer controlled from this object, though)

How do I get the rows to change their size?

A custom row height can be achieved using the rowDelegate, but this discards the default style, but it can be restored using the SystemPalette.

rowDelegate: Rectangle {
   height: 30
   SystemPalette {
      id: myPalette;
      colorGroup: SystemPalette.Active
   }
   color: {
      var baseColor = styleData.alternate?myPalette.alternateBase:myPalette.base
      return styleData.selected?myPalette.highlight:baseColor
   }
}

This restores the default background color of the rows (including alternating the row colors when desired) and the color of the selected rows, which seems to be all that is needed.
