I have a simple spreadsheet. While working on it I constantly need to
sort by different columns and I have several macros to do just that.

The problem:
For the various sorts I also need to sum the columns by their
respective categories. Hear is a simple representation of what I am
trying to do.

Item Type Qty
----------------------------
Apple Fruit 4
Pear Fruit 10
Apple Fruit 4
Potato Veg 6
Fish Meat 22

Ex: When I sort by "Item" I want the sum for each one of the
following: Apples, Pears, Potatoes, and Fish.

When I sort by "Type" I want the sum for each one of the following:
Fruit Veg Meat.

Currently after each sort, I manually insert a row between each
category and use the Sum function to get what I want. But when I sort
by something else, and then come back to a previous sort the sum rows
I inserted are no longer in the correct place. (They end up at the
bottom.)

There has got to be a better way.
Thanks
