jQuery Grid Plugin - jqGrid

Hey all,

First, my basic question: is there any way to dynamically change the core parameters that define a jqGrid (url, colNames and colModel).

Longer version: I'm trying to present several tables of completely different data without forcing the users to either drill down through multiple pages, and I can't feasibly display more than one table at a time. Some of these tables will have thousands of entries, which is why I'm interested in a plugin like jqGrid. Ideally, I'd like to present just one table at a time, and have set of navigation links that change which table is displayed. Can I do this by dynamically redifining the colNames, colModel and url settings of a single grid, or do I have to create multiple tables and use css/javascript to hide the ones that shouldn't be displayed?
