I’d like to access the active (highlighted) cell in a table in the MRML scene from the Python interactor. I thought this property might be in the vtkMRMLTableNode or vtkMRMLTableViewNode. Is there someplace else I should look? Thanks!

You can get selected column indices using [qMRMLTableView::selectedMRMLTableColumnIndices()](http://apidocs.slicer.org/master/classqMRMLTableView.html#a28f7ca3bf653ed03342789ad348f19b9)`. Feel free to add more methods (for example to return (row,col) indices, or use more Python-friendly return types) and send a pull request.

Table view also has a `selectionChanged()` signal that you can observe to get notified when selection is changed.

Thanks @lassoan. I can get the qMRMLTableView when I instantiate the widget, could you explain how to get it from the scene?

Would you like to access a table view that is in the view layout?

You can access it by calling `slicer.app.layoutManager().tableWidget(0).tableView()`.
