I read some previous posts that if specify ajaxKeys, and put the table id in the rerender attribute, it was said to rerender those particular rows entirely. But I tried with Richfaces 3.3.2.SR1, it will rerender the whole table. Is that only way to specify all the column ids in the rerender field?
you should spcify all the components inside the columns to update in all the rows which added by using rowKeys. If you will add the table id - all the table will be updated and if the column id - all the td's for that column will be updated(actually not checked but guess that Ajax keys will not works there).
