stumac summarized it pretty well. If you have done a "Compact & Repair" the database since deleting the table, you should be able to do it, if you are doing it correctly.
Of course, that is assuming that the data is in a native Access table, and not linked in from elsewhere. If it is a linked table, you will probably need to restore it from that application, whatever it may be.
However, if you have already done a "Compact & Repair", you only option is to restore from a backup.
If you do not have a backup, then you are out of luck. And it is time to start a backup schedule. Access databases can get corrupted from time-to-time, so it is essential to run regular backups.
If you do not, you are playing with fire, and it is probably only a matter of time until you get burned.
