QTableView

QTableView is a widget in the Qt framework that displays data in a table view. It is designed to present data in a tabular format, with rows and columns. QTableView works in conjunction with a model, which is responsible for storing and managing the data. This separation of concerns allows for flexibility in how data is stored and presented.

To use QTableView, you typically create an instance of the QTableView widget and set a model for it. Common model classes include QStringListModel, QStandardItemModel, and custom models that inherit from QAbstractTableModel. The model provides methods to access data, such as returning the number of rows and columns, and the data for a specific cell. QTableView then uses this information to render the table on the screen.

QTableView offers a range of features for customizing its appearance and behavior. You can set column and row headers, adjust column widths, enable or disable selection, and implement sorting. It also supports features like horizontal and vertical scrolling when the data exceeds the visible area of the widget. The widget is part of Qt's item view framework, which provides a consistent way to display various data structures.
