    Table are allocated extents,then why why index are allocated pages . can index size becomes soo huge that they have to be allocated extents?

    Tables and indexes are both allocated pages, a set of 8 contiguous pages aligned on a 64k boundary is called an extent. It's not a special structure, just 8 pages. The allocations to both indexes and tables are pages.
