How to group advanced pdf data?

I have created advanced pdf template for sales order. In item table, I want to group data by club type. club type will be wood, iron, wedge or putter. Club Sub type will be wood1, wood2…., 0iron, 1iron,…., wedge1, wedge2,…., putter0, putter1.
now group club type, and print club type and club sub type accordingly. Also club subtype should be in ascending order

Below is advanced pdf item table, Please help!
