There is a table with more than 255 columns. The database version is currently Oracle11. The restriction there is 255 columns for Advanced Compression. In another test environment, imported one partition from the 11g table into an Oracle12.1 database. We can't compress the data from this partition. The size of the partition stays the same after the compression.
