Hiding rows and columns from individual users in a shared table

Hi Niktia 

I don't know if this will be the best way for you but it may be one way;

First, getting the current user can be done using an old version of macros by defining it as a name.

=GET.WORKBOOK(35)

...and in a cell the formula =windowsUser

The workbook will have to be saved as an xlsm since it holds active content, fetching data from outside excel.
