Hmmmm - two thoughts:

1. Why not just have the table entries linked with a "next" pointer ? If necessary, throw in a "previous" pointer, too. Navigation through the table is quite easy, and you can add / delete entries simply by chaining them in the right place.
2. Have a second buffer for the table. Move upper part to buffer, then the new entry, then the lower part.
