Hi, Gents
I am not professional in ms excel and So I'm sorry if my question is simple.
I have 4 sheets witch their name is "M1" till "M4", and each worksheet contain a table, which the first column is worker name and others column is work days status
But worker change in these 4 months and so the table is not same!
how can summarise all sheets in the last sheet, in the way all worker, be in that.

the excel file is attached
