How do I display data from my table in the magento frontend?

Question

I'd like to display data from the database table on my frontend screen, I'm trying this way:

Teste/Cadastro/Block/Tabela.php

<?php
class Teste_Cadastro_Block extends Mage_Core_Block_Template
{

        public function getContent()
     {
        $cadastroModel = Mage::getModel('cadastro/cadastro');

        $collections = $cadastroModel->getCollection();

            foreach($collections as $collection)
        {
             print_r($collection->getdata(''));
        }
?>

default/template/cadastro/cadastro.phtml

...
            <div>
                    <?php echo $this->getContent(); ?>
            </div>
...

And in my config.xml I have the declared block.

Does this have to be done through a block or even an action?

Use your model like that sample:

$cadastroModel = Mage::getModel('cadastro/cadastro');

$collections = $cadastroModel->getCollection()
               ->load();

foreach($collections as $collection){
         print_r($collection->getdata());
    }
