Bug: [AOS] The desktop widget seems have strange background

[Xanonymous-GitHub]

Describe the bug
The course table widget put in desktop seems has transparent background, which is not as expected.

To Reproduce

1. In AOS, launch app and go to course table page.
2. click the menu button on top-right corner, and set current table as the widget.
3. go to the device's desktop, add an TAT course table widget
4. see that background
5. redo above in light mode and dark mode.

Expected behavior
The widget should be shown properly, which shouldn't have a transparent background.
Actually, this is similar as #103 mentioned. We can plan to migrate current widget's implementation into a more realistic way.
