[Feature Request]: Rich Text field or Sub-tasks

[SolarDesalination]

Description

In a Kanban table or grid, I would like to add sub-tasks. This could be done in two ways I think.

1. create a rich text field so I can add checkboxes in a list in the tab.
2. create a subtask function similar to how Appflowy allows subtasks for their cards/rows.
