AFAIK, a table can reside in only one tablespace ... The exception is when you have LOB columns .... In this case, you can define a LONG Tablespace ...
The Indexes can be put on its own tablespace ...
Having a long tablespace and index tablespace is possible only if you use DMS ...
You can always use multiple containers to spread the tablespace across multiple devices
Hope this clarifies ...
