> This segfaults:
> {code:java}
> tab <- Table$create(data.frame(), schema = schema(a = int32())
> as.data.frame(tab)
> {code}
> as does {{tab$a}}, i.e. just trying to extract the ChunkedArray. 
> {{Table$create(data.frame(b=1), schema = schema(a = int32())}} creates a Table with column named a, overwriting the "b" column name. 
> {{tab <- Table$create(data.frame(b=2, c=3), schema = schema(a = int32()))}}, i.e. providing fewer fields in the schema than there are columns in the data, segfaults.
> There should be some validation that the schema matches the data provided.
