Issue with integer columns: KeyError: '0'

[Roman Dolgov]

Describe the bug
I try to create table with pandahouse:

  create_table = f"CREATE TABLE data.sma({fields}) ENGINE=Log"
  ph.execute(create_table, connection=connection)

and got as a result:

Traceback (most recent call last):
  File "./SMA_test_alter.py", line 128, in <module>
    main()
  File "./SMA_test_alter.py", line 125, in main

To Reproduce

create table = "CREATE TABLE data.sma(`3` Float64 , `4` Float64 , `5` Float64 , `6` Float64 , `7` Float64 , `8` Float64 , `9` Float64 , `10` Float64 , `1-2` LowCardinality(String), `1-3` LowCardinality(String), `1-4` LowCardinality(String), `1-5` LowCardinality(String), `1-6` LowCardinality(String), `1-7` LowCardinality(String), `1-8` LowCardinality(String), `2-3` LowCardinality(String), `2-4` LowCardinality(String), `2-5` LowCardinality(String), `2-6` LowCardinality(String), `2-7` LowCardinality(String), `2-8` LowCardinality(String), `3-4` LowCardinality(String), `3-5` LowCardinality(String), `3-6` LowCardinality(String), `3-7` LowCardinality(String), `3-8` LowCardinality(String), `4-5` LowCardinality(String), `4-6` LowCardinality(String), `4-7` LowCardinality(String), `4-8` LowCardinality(String), `5-6` LowCardinality(String), `5-7` LowCardinality(String), `5-8` LowCardinality(String), `6-7` LowCardinality(String), `6-8` LowCardinality(String), `7-8` LowCardinality(String)) ENGINE=Log"

ph.execute(create_table, connection=connection)

Expected behavior
created table(b/c I just copied create_table string and it works if I manually push it using ch client.
