Pagination in this web is not working properly

There are 3 pagination tables in this web.
price_computer_category1~3.
Starting from first price_computer_category1, elements in price_computer_category2~3 are collected correctly.
And data scraping is completed where it should move to another page in price_computer_category1.
Any solution?
