interesting, thanks for the code! I can reproduce the issue.
heres a working version, note how the schema used for create table and
append are all aligned
```
# working
from pyiceberg.catalog import load_catalog
import pyarrow as pa
catalog = load_catalog(**dict(type="in-memory"))
df_1 = pa.Table.from_pylist([
{"name": "one", "my_list": ["test"]},
{"name": "another", "my_list": ["test"]},
])
pyarrow_schema = df_1.schema
# create table
catalog.create_namespace_if_not_exists("test")
catalog.create_table_if_not_exists("test.table", pyarrow_schema)
# append data
catalog.load_table("test.table").append(df_1)
catalog.load_table("test.table").scan().to_arrow()
# append more data
df_2 = pa.Table.from_pylist([
{"name": "one"},
{"name": "another"},
], schema=pyarrow_schema)
catalog.load_table("test.table").append(df_2)
catalog.load_table("test.table").scan().to_arrow()
```
