Merge two queries - same columns on each data set with different data

Hello all!

I am currently have an excel document (updated daily) with two sheets containing my relevant data.

Currently I am using power query to extract two tables, one from each sheet, resulting in two tables in the same format and same column headings.

What is the most efficient way to combine these into a single table /  query for my model.

I need to have "monthly data" as a single table.

Thanks in advance

Mike
