table deleted unfortunately

hi experts i am new to abap, when i was working with

abap dictionary using MARA table , i have used append structure,

while doing that unfortunately, the table got locked. i has given

one information saying that i have to readjust table.

i went to SE14 and did that and i relesed lock.

then the MARA table got deleted from database

(but it is there in data dictionary)

is there any way to create only one table in

data base.

thamks in advance
