Python-PyQt5-使用SQL自动填充QTableWidget

Question

早晨/下午/晚上

我以前遇到过砖墙，我能够使用QLineEdit来为您提供自动填充选项，例如：

Autofill（无法嵌入图像，因此无法链接）

以前，这些值是在列表中排序的，并且可以使用QCompleter和QStringListModel来实现。

已将所有QLineEdits的表单移至现在的QTableWidget。我想通过QLineEdit达到与以前相同的效果，如果在字段中键入带有标签的“配件”，它将与以前一样执行。以前存储在列表中的值现在在SQL DB中。

预先感谢:)对不起，有点混乱

编辑：被标记为欺骗并给予sqlite3 table into QTableWidget, sqlite3, PyQt5 无法看到它与我的代码的对应关系，我丢失了什么吗？

Edit2：更改了文本，使其更加不稳定
