I use PrimeNg 15.2.0 version. I have rowsPerPageOptions change problem. I have a p-table which is empty in the beginning when page is loaded and it has paginator with dropdown options. After setting filter and clicking import data button, it is gotten data for the table. Now I can choose any given data from paginator dropdown options and it will present me that amount of data rows depending on my choice in paginator dropdown.
