Add tasks inside tables

It would be nice to have support for tasks inside table cells, and it would also be a good workaround for a Kanban, the workaround mentioned in the Kanban feature suggestion is not useable, as it breaks the main purpose of Kanban - Easy visualization of tasks.

It could also have a few more use cases, like:

- Habit trackers
- Goal management through OKR or SMART frameworks, or simply organize them by quarter
- Visual Einsehower Matrix
- Pomodoro tables
- Simple Project Management
