Update table Automatically by inserting into another

So I have two tables and only want to insert the data once. The second table is more detailed with more columns so I want to see if I can reference the first table to populate the correct columns in the second. Is there a way to automatically create a row in the second table when a row is completed in the first?

example

Job #	Unit #	Employee	Equipment
1	TT 01	Mike Wilson	Trailer
2	TT 02	Dan M	Goose neck Truck
3	TT 03	Dave C	Truck
4	TT 04	Chris P	Truck

to populate

Job #	Description	Unit #	Employee	Billable Hours	Equipment

Then obviously you would need to go in manually on the second table to fill out the description and Billable hours

Not clear about what you want, hope it works, let me know if not suits your requirement..
