cassandra cqlsh无法显示column_family的自定义属性

Question

假设我有一个名为kv的column_family，并且我想向表中添加一个自定义属性new_attribute，所以当我使用命令desc table kv时它将显示如下：

CREATE TABLE ks1.kv (
    k text PRIMARY KEY,
    v text
) WITH bloom_filter_fp_chance = 0.01
    AND caching = {'keys': 'ALL', 'rows_per_partition': 'ALL'}
    AND comment = ''
    AND compaction = {'class': 'SizeTieredCompactionStrategy'}
    AND compression = {'sstable_compression': 'org.apache.cassandra.io.compress.LZ4Compressor'}
    AND crc_check_chance = 1.0
    AND dclocal_read_repair_chance = 0.1
    AND default_time_to_live = 0
    AND gc_grace_seconds = 864000
    AND max_index_interval = 2048
    AND memtable_flush_period_in_ms = 0
    AND min_index_interval = 128
    AND read_repair_chance = 0.0
    AND speculative_retry = '99.0PERCENTILE'
    AND new_attribute = ***;

请注意最后一行。我想证明这一点。但是似乎在发出命令desc table kv时，cqlsh不会将字符串发送到cassandra服务器。相反，它似乎从python cassandra库中获取结果。我应该如何让cqlsh支持呢？ （假设我已经在cassandra服务器中实现了这样的属性）
