### Rationale for this change
For now, we can regard the from_pydict as a method for creating Table with
column-like data, since its input is a mapping of field to array. We also have
from_pylist which can create Table with row-like data. But from_pylist requires
that data and field are bounded, because it takes a dict as a row. It's a
little bit inflexible for use, because we may have list of list as row data and
we need to construct list of dict with schema name to use from_pylist.

If tests are not included in your PR, please explain why (for example, are
they covered by existing tests)?

Please uncomment the line below (and provide explanation) if the changes fix
either (a) a security vulnerability, (b) a bug that caused incorrect or invalid

contract is upheld). We use this to highlight fixes to issues that may affect
users without their knowledge. For this reason, fixing bugs that cause errors
don't count, since those are usually obvious.
