How to create a table during the module installation

Question

I'm trying to create a module for Drupal 7 and I need to create 3 tables and populate it. But first i need to create it.

In the file mymodule.install I have got

function mymodule_install() {

}

function mymodule_uninstall() {

}


function myodule_schema() {
  $schema['mymodule_table'] = array(
    'description' => t('First table'),
    'fields' => array(
      'id' => array(
        'description' => t('My unique identifier'),
        'type' => 'int',
        'unsigned' => true,
        'not null' => true,
      ),
      'list' => array(
        'description' => t('list'),
        'type' => 'varchar',
        'not null' => true,
      ),
    ),
    'primary key' => array('id'),
  );
  return $schema;     
}

What am I doing wrong? Every time I test the module, I disable it -> uninstall -> Performance clear cache -> enable it.
