Here is one approach that does not require VBA for even a filter:

After you have added your weekly updates to the table, sort it by ALT. This
will cluster the data by the value of ALT. After the sort, copy the rows (or
columns) with the same ALT into sub-tables.

Is there a way, without using VBA code, that I can create an advanced filter
(or similar process) that recalculates automatically when the data table
changes? For example I have a table with values for Alt, GPH, and TAS. I add
new data to the table each week. I would like to create subset tables for
each unique value of Alt. All the unique values of Alt are known.
