How to scrape data from main page and detail page at once in a one row

I need to scrape details from main page (Ex:Product list page) and detail page (Ex: Product detail page) and export as a one row in csv file.
Because some details are only available in main page, like "seller" (product list).

I need to get main and detail page data as a one row because I will get all the results through paging.

Any of you have a sample or sample web link that I can see related to this?
