newbie in datagrid

Hi, I'm new to the world of PEAR. I've seem an example of what could be done with PEAR packages and it was great. Now i would like to use it on my website by i'm quite confused. I would like to display a simple table - with 10 rows per page. - if there are more records (than 10), some arrows images should be displayed somewhere to allow user to switch among pages - to allow sorting on columns - to customize the render - to connect to postgreSQL to do that i was thinking to use : - structures/datagrid however, i have some problem to know what will be the good DB package for me. what can i tell, it's that i have a global variabl $db which represents the pg_connect to postgreSQL database. so if $db exists, therefore we are already connected to db. i would like to use a package like that : package_db = $db; package_query = $query; and get the output to a render like HTML table with paging and customization of colors,... So, which DB object/package do you advise me and how to use it ? moreover, which render could be the most interesting for me ? thanks a lot, Al.
