Query result to a table

I have a table: Table(blah, blah, date1, date2, differenceOfDays,
blah)

I made a query using MS Access, which subtracts the dates to give the
number of days in between.  And it shows the correct values on the
query screen (made up of Date1 Date2 differenceOfDays).

My question is, how do I make the result (which is in the query) to go
into the actual table cell?
