## Description
This PR started with this goal:
- Deleted the unreadable `derived.test.js` (4668 lines) file and split
each suite to its file.
- Moved all `derived.js` related specs in widget folder to __tests__
folder
Later we found that `testRegex` in `jest.config` will treat anything
inside `__tests__` as runnable, so we modify this rule and are moving to
a consistent naming for our unit tests(any file ending with `.test.` or
`.spec.`
This refactor aims to improve maintainability and ensure that the table
widget's derived properties are thoroughly tested.
Fixes #`Issue Number`

Fixes `Issue URL`
