Swap Rows based on Comparison

Question

I have Datatable I want to compare the values and swap the rows
original table1

PName	CN	CR	DS
diff	2.4	2.8	1.5
prg	1.7	0.5	2.2
new	1.2	2.1	1.7

 
"CN< 1.6 AND DS >1.5" 
then that has to be moved to top
output

PName	CN	CR	DS
new	1.2	2.1	1.7
diff	2.4	2.8	1.5
prg	1.7	0.5	2.2
