Advise widgets for creating and editing tables by the user on the site?

Question

css

In general, in my application, the user edits and creates tables (schedule). These tables must be stored in the database.
What widget do you recommend for creating these tables? And in general, how can such a scheme be implemented?
Thank you in advance for your answer and sorry for the badly worded question)

Answer 1

Create a table template and, having received data about the table in JSON, draw it on the page.
Creation - use the same template with reactive editing (add/remove rows/columns, etc)
