How to get a table creation script in MySQL Workbench?

I cannot find such an option either, at least in the Community edition.

I suppose this corresponds to the Reverse Engineering feature, which, unfortunately, is only available in the commercial edition (quoting) :

reverse engineering a database directly from a MySQL server applies to commercial versions of MySQL Workbench only.

Still, you can use plain-SQL to get the create table instruction that will allow you to create a table.

For instance, the following query :

show create table url_alias;

when executed on a drupal database, would give, when using right click > copy field content on the result :

'CREATE TABLE `url_alias` (
  `pid` int(10) unsigned NOT NULL auto_increment,
  `src` varchar(128) NOT NULL default '''',
  `dst` varchar(128) NOT NULL default '''',
  `language` varchar(12) NOT NULL default '''',
  PRIMARY KEY  (`pid`),
  UNIQUE KEY `dst_language` (`dst`,`language`),
  KEY `src_language` (`src`,`language`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8'

Unfortunately (again), MySQL Workbench adds some quotes everywhere when copying this way :-(

EDIT: Using MySQL 8.0, there is an option to right click > copy field (unquoted) on the result to get the desired result without quotes.

In the end, the simplest solution, except from staying with MySQL Query Browser, will most likely be to connect to the database, using the command-line client, and execute the show create table query from there :

mysql> show create table url_alias\G
*************************** 1. row ***************************
       Table: url_alias
Create Table: CREATE TABLE `url_alias`
