/// A trait representing a table-based Qt model.
///
/// [`QTableModel`] provides an interface for table-like data structures
/// that are exposed to Qt through the Model-View concept.
/// <https://doc.qt.io/qt-6/qtquick-modelviewsdata-modelview.html>.
///
/// This trait requires the `qobject` macro to set up the correct Qt proxy.
/// The macro will further generate functionality in the form of the
/// [`QTableModelBase`] trait that supplements the [`QTableModel`] functionality.
///
/// ## Design
///
/// - The model owns items of associated type `Item` that has to implement
///   the [`QModelItem`] trait. Roles are derived from the [`QModelItem`]
///   implementation.
/// - Mutation methods are provided in an **unnotified** form, meaning
///   they modify the underlying data without emitting Qt model signals.
/// - These methods are used by the automatically implemented [`QTableModelBase`]
///   trait to create methods that collaborate the UI about changes in collections.
///
/// As a minimum you have to implement the methods [`QTableModel::row_count`],
/// [`QTableModel::column_count`] and [`QTableModel::get`] to create a readable
/// list model. Further methods can be implemented to make the model fully mutable.
///
/// Methods that do not return an [`Option`] or a boolean value must succeed
/// and perform exactly the operation described in the documentation to avoid
/// invalidating the synchronization between any views and the underlying data.
/// No additional structural changes may occur outside the provided functions.
///
/// **Note, that default implementations may `panic!`** if the corresponding method is
/// not overridden. It is your responsibility to make sure that these functions are
/// not called from QML.
///
/// ## Example
///
/// ``` ignore
/// use qtbridge::qobject;
/// #[qobject(Base = QTableModel)]
/// mod backend {
///     use qtbridge::{QTableModel, QTableModelBase};
///
///     #[derive(Default)]
///     pub struct Backend {
///         string_data: Vec<Vec<String>>,
///     }
///     impl QTableModel for Backend {
///         type Item = String;
///
///         fn len(&self) -> usize {
///             self.string_data.len()
///         }
///         fn column_count(&self) -> usize {
///             self.string_data[0].len
///         }
///         fn get(&self, index: (usize, usize)) -> Option<&Self::Item> {
///             self.string_list.get(index.0)?.get(index.1)
///         }
///     }
/// }
///
/// ```
///
/// The table model can be used in QML views as follows
/// ``` qml, ignore
/// TableView {
///     model: backend
///     delegate: Text {
///         required property string value
///         text: value
///     }
/// }
