您可能想要熟悉模型/视图框架。简单来说，模型是你拥有的实际数据，它独立于如何显示它。视图是模型的特定显示实现。所以你可以使用像QStandarItemModel这样的模型来存储你的String +数字数据并在QTableView中显示模型。

You may want to familiarize yourself with the model/view framework. To put it simply, a model is the actual data that you have and it is independent of how it should be displayed. A view is a particular display implementation of a model. So you could use a model like the QStandarItemModel to store your String+number data and display the model in a QTableView.

来自Qt网站的模型/视图教程 here
QStandardItemModel类此处。里面有一个简单的例子。

Model/View Tutorial from Qt website here QStandardItemModel class here. Has a simple example inside there.

并且，为了写入和读取数据到文件，我建议你可以使用QXmlStreamWriter / Reader类。请参阅 QT xmlwriter / xmlreader

And, for writing and reading the data to a file, I suggest you could use the QXmlStreamWriter/Reader classes. Refer to QT xmlwriter/xmlreader
