You can use a query with an expression that combines the 2 colums. If you rightclick in a field, when designing a query, you can use the build option. In the build option, find the function you need, use & (to combine fields or expressions) and the other field
At least, if you are using 2 colums in stead of 2 rows like you describe. (colums are vertical, fields in 1 record, rows are horizontal, the records in a table)
