Helps you implement a table with datamatted storage.
This helper is obsolete. If you are writing a new module, please consider using the table_tdata helper instead.
This helper helps you implement a table where all the indexes are expected to be stored within the agent itself and not in some external storage location. It can be used to store a list of rows, where a row consists of the indexes to the table and a generic data pointer. You can then implement a subhandler which is passed the exact row definition and data it must return data for or accept data for. Complex GETNEXT handling is greatly simplified in this case.
