RAM, this is expected behavior. Once space is allocated to an object it
generally takes DBA action to free the space whether at the table, index, or
data file level.
Run a truncate on the table to free up the unneeded extents.

Subject: Space explanation
Hi
I created a table for testing and inserting rows into it when the insert
process failed as the tablespace reached maximum limit of 32G - that happened
couple of days ago. However, there are no rows in the table, but space occupied
shows as real high with the tablespace itself full. Does anyone have an idea?
There are couple of other tables in the tablespace but they occupy just few 100
blocks. 12c
1 select table_name, NUM_ROWS, last_analyzed, blocks from dba_tables
2* where table_name = upper('wvce')
11:14:17 SQL> /
TABLE_NAME NUM_ROWS LAST_ANAL BLOCKS
