Make individual tables from one large data set

I have an excel file with n rows of data.  I need to compile the data onto a separate sheet into n number of tables.  Here is what I mean:

The main data file has three category columns.  I need to do the following:

1. First, look at the unique values in category1
2. For each unique value I need to find the unique values in category2 and then category 3 and sum them up.
3. I need to then build a table on anoter sheet for each of the unique values in category 1.  

Please see the attached sample for the initial data and the resulting tables.

Do you have a set list of what will be in the categories?  For example, do you know that Category2 will always be one of "Red" or "Blue"?  Or are these free-text kind of entries?
It sounds like a pivot table would do this for you pretty easily.

  That looks like it will solve the problem, but I was curious as to how you got the pivot tables to go horizontal vs. vertical.  Can you tell me how you did that so that I can replicate the pivot table?  I have been unsuccessful at finding that option.
