在tableview中动态添加和排序python

Question

从简单字典中读取数据d = {key：['desc'，dateadded]} 目标是将数据添加到表视图中，并按列表中的日期排序。尝试将表放在主窗口上时，无法获取任何数据添加。

问题在于我如何将表放置在主窗口上。我有一个带表的工作小部件，现在正试图组合这两个文件。目前该应用程序崩溃。不要你写代码，但在正确的方向推动将是一个很大的帮助。

Answer 1

通过代码挖掘后，我发现QTableWidget的，而不是一个视图需要线

self.tableView = QtGui.QTableView(self.centralwidget) 

。这允许我设置值等。
