link auto-filter to different cell

How can we program an auto filter a table linked to a cell. For example I have a table with 4 columns (A9:D20) and the 2nd row of the sheet is the filter item (A2, B2, C2 & D2).

Lets say column A has a list of months, column B has a list of names, column C is sales figure, column D is the customer. How can I filter let say for the total sales of Mr. X in the month of January.

I came across a code like this but I don't know how to apply it to my sheet. Of course this code is referring to a different table and links but I just need to learn how to apply this code to my sheet:

Activesheet.AutoFilterMode = False
Activesheet.Range("D2:D60").AutoFilter 1, Activesheet.Range("A2").value
AutoFilter.xlsx

Izandol, is it possible to program the table to be filtered just like this one but in another sheet. Each sheet shall auto filter in the sheet and the original table is not effected and still list all the item in the original table.
