New Post: Copy Cut and Paste the set of rows from one place to other in a excel sheet using PHPExcel

I am trying to cut and copy a range of rows from my excel sheet (about 2346 rows) and paste it in down at the bottom of the sheet. I would like to cut and copy 6-80 rows,331-354 rows and then paste them in bottom,
I would like to know a good way to perform this operation using PHPexcel methods. Please give me suggestions.

Thank you
