Array doesn't seem to work

[knoguchi]

By looking at the base.py it seems Array is supported, however I got an error

can't render element of type <class 'sqlalchemy_clickhouse.base.ARRAY'>

Steps to reproduce

1. create a table

CREATE TABLE default.xxx ( name String,  phone Array(String)) ENGINE = Memory()

 #!/usr/bin/env python

# Test engine and table
from sqlalchemy import *
from sqlalchemy.engine import create_engine
from sqlalchemy.schema import *
from sqlalchemy_clickhouse.base import dialect
engine = create_engine('clickhouse://default:@localhost:8123/default')
tbl = Table('xxx', MetaData(bind=engine), autoload=True)

ddl = CreateTable(tbl).compile(dialect=dialect())
print(ddl)

Maybe my specific case -- print CREATE TABLE stmt isn't supported?
