It's unusable in real application because header should be fixed and not hidden when user scrolling the data.
For what it's worth, QML types VerticalHeaderView and HorizontalHeaderView now exist
Hi this is a very informative tutorial. Thank You ! Can you please create tutorial for scrolling some middle columns of QML table view horizontally with outer columns should be freeze (not scrollable).
Hi Daniel,
How to add a button in every row to edit data/delete that row?
ugh seriously who builds & releases a tableview without headers.... i wonder if it has auto scrollbars now.
Hi, is it possible to have checkbox in one of the row?
How can i also find on which row i clicked/tapped?
You can add QML check box in the delegate. For clicks there are many ways like MouseArea or some signals from TableView itself. I would recommend learning the basics about QML and most of these things will suddenly make sense.
If you want to find out which item was clicked, add a MouseArea on your delegate, and in the onClicked handler reference the model.row and model.column properties.
How to make first row constant
Hi Daniel,
Do you know if I want to use QSortFilterProxyModel instead of a TableModel which inherits from QAbstractTableModel, how can I do that? I know that I have to setSource(TableModel) for the proxy object but I don't know how can I use it in the QML !
Why do table is blinking when its colored in red and green? Because of this it seems very unusable for real applications.
Thanks.

Hi,
how it is possible to add a row to the TableView?
Thanks,

You can reimplement insertRows in your model as shown in docs : doc.qt.io/qt-5/qabstractitemmodel.html#insertRows . In that method just make sure to call beginInsertRows and endInsertRows. Any view attached to that model will update with the new changes to the model. Hope this helps.
@@LearnQtGuide Thank you.
I would not use the QAbstractItemModel API for that, if you want to do this from the QML side. Instead, simply add a specialized Q_INVOKABLE method on your model, and call that from QML to do the insertion. The QAIM API is not suitable for direct consumption by application logic.
Hello!! i needed some help to display Sqlite data into this TableView.. How is it possible? or is there any other way to display Sqlite tables and refresh them as the new entries occur? Please help ! thank you :)
Use a QSqlTableModel as your model, instead of a custom made QAbstractTableModel derived class. It won't automatically update itself though, you'll have to have some type of signal or callback that tells you when to requery.
@@AndreSomers Thank you very much :)
Thanks for help!
Never understood why people start tutorials with "Let's create a new project!", most of us have a project, lets go! Its like if I taught somebody how to setup some windows feature and started my video with "Ok, let's start by installing windows"
