Push-outputbinding for table using wrong type

Is there anyway to request a field be int64 instead of a int32? I am selecting some azure resources and storing them in a table. When I call Push-OutputBinding -Name OutTable -Value $tableRows for a table that does not exist the function creates the column as INT32 and of course it blows up. Is there anyway to provide some details about the columns that should be created? Or do i need to pre-create the table before loading data to it?

Thanks
Scott.
