Dear Monks

I am trying to convert the table from one format to another format by adding some columns. For given account block, I have 2 columns 'Px and Qx'. I like to add 'Qy and Py'. P and Q makes a pair. and Px-Qx is sorted by column Px and Qx respectively. Qy-Py should be sorted by Qy and Py respectively. The data for Qy-Py is taken from Px-Qx without modification except changing the order within the account block.

Given

A  Px Qx
a1 p1 q5
a1 p1 q6
a1 p2 q4
a2 p3 q9
a2 p2 q8
a2 p2 q9
Should be converted to: 
A  Px Qx  Qy Py
a1 p1 q5 q4 p2
a2 p1 q6 q5 p1
a1 p2 q4 q6 p1
a2 p3 q9 q8 p2
a2 p2 q8 q9 p3
a2 p2 q9 q9 p2

Thanks
artist
