Grouping PO Lines according to Tax Codes

Question

Hi All,
I have a query,in my report when i pass the po_number,it prints the po details and line details.For each line i have taxes also.
For Example if i have 5 lines (1,2,3,4,5). For 1st,2nd and 3rd line's have a,b,c,d as the taxes and for 4th and 5th having a,b as taxes.
Now i need to print the report in such a manner that,first i need to print all the three lines (1,2,3) and then need to print there taxes(a,b,c,d).
and then need to print 4th and 5th line and followed by taxes(a,b) which the both line contains.
Waiting for you valuable comments..
Thanks in Advance.....
