   I have corrected the code so that `pylist` is meant to be structured as a list of dicts, one dict per row. If the column name is missing from the schema or from the data, `None` is put in.
   
   If the schema is not given in `from_pylist(),` the keys from the first dictionary are used to define the names of the columns in the Table/RecordBatch.
   
   Also I saw that there are only a few examples added in the [docstrings](https://arrow.apache.org/docs/python/generated/pyarrow.Table.html#pyarrow.Table). I think they are a great way to understand the codebase as they are easy to locate and to use. I would be happy to add them as a part of the [Documentation Improvements](https://issues.apache.org/jira/browse/ARROW-13407) or as a separate JIRA issue.
