Usually, a QWidget is used to display data in most data-driven +applications. Use a table view to display your data. + +The first step is to add a horizontal layout with just a QTableView. You +can create a QTableView object and place it inside a QHBoxLayout. Once the +QWidget is properly built, pass the object to the QMainWindow as its central +widget. + +Remember that a QTableView needs a model to display information. In this case, +you can use a QAbstractTableModel instance. + +.. note:: You could also use the default item model that comes with a + QTableWidget instead. QTableWidget is a convenience class that reduces + your codebase considerably as you don't need to implement a data model. + However, it's less flexible than a QTableView, as QTableWidget cannot be + used with just any data. For more insight about Qt's model-view framework, + refer to the + `Model View Programming <http://doc.qt.io/qt-5/model-view-programming.html>` + documentation. + +Implementing the model for your QTableView, allows you to: +- set the headers, +- manipulate the formats of the cell values (remember we have UTC time and float +numbers), +- set style properties like text alignment, +- and even set color properties for the cell or its content. + +To subclass the QAbstractTable, you must reimplement its virtual methods, +rowCount(), columnCount(), and data(). This way, you can ensure that the data +is handled properly.
