This post is about a problem that occurs sometimes in af:table when we use icon in any column, I am not sure that it is a bug or not but sometimes table is not fully stretched on first load and last row doesn't appear properly on page but after refreshing page again problem is solved.
Recently I have seen a question on OTN forum about this and sharing that information here so that if anyone is facing same problem then look into it
So if you have to show specific number of rows and if you are facing this problem then set autoHeightRows property to -1 and set height in inlineStyle property of af:table
