I get this error that I do not understand. Does anyone know what is happening
and how to get around it
>>> import atpy
>>> t = atpy.Table()
>>> name = ["aa","bb","cc"]
>>> t.add_column("name",name)
>>> k = [1,2,3]
>>> t.add_column("num",k)
>>> t
<Table name='None' rows=3 fields=2>
>>> name = ["aaa","bbb","ccc"]
>>> p = atpy.Table()
>>> p.add_column("name",name)
>>> p.add_column("num",k)
>>> t.append(p)
Traceback (most recent call last):
