One of the problems is what should be included. Indexes? Policies? Constraints?
Another problem is that while a function or view definition is a single SQL statement, a table definition could consist of more than a single statement, depending on the answer to the previous question.
No unsurmountable questions, but someone would have to come up with a clear design and implement it.
Because you can already get all the other DDL relevant to creating a table (like indices, primary and foreign keys, grants), ISTM that just a plain CREATE TABLE with column DEFAULT clauses is what pg_get_tabledef() should create.
A comprehensive "recreate everything related to a table" function should be left as an exercise for the DBA.
