[FEATURE] Add options to TablePrompt

[TheItsNameless]

Feature description
Currently, TablePrompt is very basic. Features like marking a cell as immutable are missing.

Additional Information
It should be possible to create cells either by inputing a string (which will be the cell content) or a dictionary (may be an object as well) which has the attributes:

• content
• immutable
• type

If only a string is used, it will be assumed as not immutable and the type will be string.

An example:

{"colum 1": [{"content": "this stays as is", "immutable": True}, "type here"]}
