Could you provide the full column type? You can use
`print(table.column('col_name').type)` to print it out.
I was not able to reproduce that conversion issue with the following code on
PyArrow 7.0.0 (nor 6.0.1):
```python
import pyarrow as pa
import pandas as pd
data = [[('x', 1.0), ('y', 0.0)], [('a', 2.0), ('b', 45.0)]]
ty = pa.map_(pa.string(), pa.float64())
table = pa.table({'col': pa.array(data, type=ty)})
table.to_pandas() # Works fine for me.
```
Maybe verify that that works for you and double check your pyarrow version
as well.
