Sistema de filtro de tabela dinamica PHP

Prezados boa tarde,

Preciso de construir um sistema de filtro para a tabela gerada automaticamente através de uma pesquisa select e while para uma tabela comum html.

Penso em fazer da seguinte maneira:

* Colocar a linha onde entram os parâmetros do filtro dentro de um formulário onde quando acionado passam as informações via $_POST para dentro da mesma página (pois o action do formulário aponta para mesma página).
* Assim será possível utilizar o $_POST para realizar os filtros dentro do recordset nos select. Que por sua vez estarão dentro de um if(isset()) para verificar sua existência e selecionar qual select mostrará na tela(com todos os registros ou com filtro).

O problema é que ao acionar o botão FILTRO, não está submetendo o formulário. Abaixo segue código com o formulário e tabela:

< table id="tabela" width="100%" border="0">
