Minor issue: space needed before table_options

[shelly-li-sl]

When using gorm:table_options with migrator, the generated 'create table' clause looks like the following, a space is missing before keyword 'TABLESPACE'.

===gorm:table_options
DB.Set("gorm:table_options", "TABLESPACE SYSAUX").AutoMigrate(&JsonRecord{});
