in fact you need two structures : one core structure containing all the data, called the model, and a UI component displaying the data from the model. It is bit more complex and time consuming to setup than an excel/libreoffice spreadsheet, but much more lightweight and offers you more control and more protection on how data are displayed or edited, which cells are editable.
creating a view in
TableView
{
id: tableView
anchors.fill: parent // or whatever anchoring/positionning/layout you want
model: yourTableModel // should be declared nearby
}
Please note that TableView on it's own doesn't provide horizontal and vertical headers, you have to add VerticalHeaderView and HorizontalHeaderView manually.
https://doc.qt.io/qt-6/qml-qtquick-controls-verticalheaderview.html
for the model, you have two options :
either you subclass QAbstractTableModel, adding a QML_ELEMENT macro after Q_OBJECT, and declaring those source files in a qt_add_qml_module directive in CMakeLists.txt The TableView documentation provides a minimal example of a model that can be used in a QML view : https://doc.qt.io/qt-6/qml-qtquick-tableview.html
or you can use the ListModel QML element if your model isn't much complex.
Option one is usually advised for production. Option two is often used by UI dev to supply a sample model to work on the view itself.
