I wrote my first jquery plugin; rcGrid, the RondaChurros Grid. rcGrid is a lightweight, jquery + json + ajax editable grid with support for crud, paging, filtering, sorting –and– easy implementation of custom edit forms.
Look at some samples of rcGrid here
The custom edit forms (just some simple html) gives you an easy to set up custom input form that is bound to your database !
