Would you be able to advise how to compare table columns in a pytest function properly? Experiencing a challenge when comparing columns.

Test:
```python
def test_duplicate(fresh_db):
    table = fresh_db.create_table(
        ""table1"",
        {
            ""text_col"": str,
            ""float_col"": float,
            ""int_col"": int,
            ""bool_col"": bool,
            ""bytes_col"": bytes,
            ""datetime_col"": datetime.datetime,
        },
    )
    dt = datetime.datetime.now()
    b = bytes('hello world', 'utf-8')
    data = {""text_col"": ""Cleo"", 
            ""float_col"": 3.14,
            ""int_col"": -2,
            ""bool_col"": True,
            ""bytes_col"": b,
            ""datetime_col"": str(dt)}
    table1 = fresh_db[""table1""]
    row_id = table1.insert(data).last_rowid
    table1.duplicate('table2')
    table2 = fresh_db[""table2""]
    assert data == table2.get(row_id)
    assert table1.columns == table2.columns    # FAILS HERE
```

Result:

Failure is due to column types being named differently -- e.g. 'FLOAT' vs 'REAL', 'INTEGER' vs 'INT'. How should I go about comparing columns while accounting for equivalent types?

Or did I miss out something in my duplication code correctly? Here's how I did it: in `db.py`, I've added the following code:
```python
class Table(Queryable):
    [...]
    def duplicate(
        self, 
        name_new: str
    ) -> ""Table"":
        """"""
        Duplicate this table in this database.

        :param name_new: Name of new table.
        """"""
        assert self.exists()
        with self.db.conn:
            sql = ""CREATE TABLE [{new_table}] AS SELECT * FROM [{table}];"".format(
                new_table = name_new,
                table = self.name,
            )
            self.db.execute(sql)
        return self.db[name_new]
