is that possible to create a hbase table without adding column family, for instance create 'emp','personal data','professional data'

personal data & professional data are the column family, i want to add fields to table without adding column family

for example 

        HTable hTable = new HTable(config, "TableName");
        Put p = new Put(Bytes.toBytes("ROW"));
        p.add(Bytes.toBytes("VALUES"); 
        //only the values need to be added to the column without column family.

Every HBase table must have at least one column family. Every piece of data in HBase is in a Cell (KeyValue) which has a row, column family, column qualifier, timestamp, and a value. The column families are defined statically when creating the table and cannot be altered without disabling the table. However, you can dynamically create any columns you want inside a column family - in fact each row could have it's own columns.
