105901 Ajax my data

I ahve about 10 pages in my php website which include paginated lists, each list contains about 5 columns of data. The pages are now paginated, something like: Previous 1 - 2 - 3 - 4 - 5 Next Each page now displays 20 lines. I would like to change that to the exact same thing, but without reloading the page, so that the next set of results can be displayed using Ajax.
