register_pandas_dataframe() cannot register with complex data types

When using the `register_pandas_dataframe()` method from the TabularDatasetFactory, I am getting an error
```
UserErrorException: UserErrorException:
Message: Cannot register pandas dataframes with columns containing complex data types. Encountered column with type:
InnerException None
ErrorResponse
{
"error": {
"code": "UserError",
"message": "Cannot register pandas dataframes with columns containing complex data types. Encountered column with type: "
}
```
I can see why I am getting this error, but what's very frustrating is on the [documentation page](https://stackoverflow.com/questions/71919389/azureml-tabulardataset-to-pandas-dataframe-returns-invalidencoding-error) and on the [user guide](https://stackoverflow.com/questions/71919389/azureml-tabulardataset-to-pandas-dataframe-returns-invalidencoding-error), nowhere does is show that some datatypes are not supported (like a numpy array).

A small table in the documentation showing unsupported datatypes would greatly benefit the user.
