如何逐行向qtablewidget插入数据
How insert data to qtablewidget row by row
我不明白如何将数据逐行放入QTableWidget。我从 lineEdit 中获取数据，然后将其放入 table，但是当我尝试添加另一个人时，它会重写以前的数据，但我需要将其放在下面的行中。我想我应该用“行”做点什么
这是我的代码

假设你想递增地插入项目，你应该创建一个实例属性，用于从第一行开始（顺便说一下，是 0，不是 1）然后每次递增 1 .
无论如何，这应该不用pyuic创建的文件来完成，因为这些文件是为了保持 不变 。出于很多原因，强烈建议不要编辑它们，并且认为这是不好的做法。详细了解如何在 using Designer.
时正确 使用这些文件
因此，再次重建您的 .ui 文件（在下一个示例中，我假设您已经生成了一个名为 ui_mainwindow.py 的文件），然后创建类似于以下内容的实际脚本：

cur = conn.cursor()
cur.execute('CREATE TABLE if not exists disp_list(disp_name text, disp_surname text, disp_date text)')
