Check also related question: Is prefixing each field name in a table with abbreviated table name a good practice?
As I mentioned in my answer; the concept of prefixing field names with the table name comes from the old time of legacy systems when each field across the whole database needed to be unique. That is not required any more by the modern systems so it is just a convention that is no longer necessary. As mentioned by Think Before Coding "The table name already gives the context. No need to prefix columns name with it"
