hook_menu, display a form at the top and table at the bottom
Here's an implementation of my earlier suggestion to append the table as a form markup and rendering the form with table in the menu callback

/**
 * Form builder function
 */
function mymodule_form() {
  $form = array();
  $form['sometext'] = array(
    '#type' =&gt; 'textfield',
    '#title' =&gt; t('Some random textfield'),
    '#default_value' =&gt; 'Hello world',
  );
  $form['tablemarkup'] = array(
    '#markup' =&gt; my_module_table(),
  );
  return system_settings_form($form);
}


/**
 * Callback function for returning form with themed table
 */
function mymodule_page() {
  $output = array();
  $form_data = drupal_get_form('my_module_form');
  $output = drupal_render($form_data);
  return $output;
}

/**
 * Function to return themed table.
 */
function my_module_table() {
  $header = array(
    'data' =&gt; 'Table title',
  );
  $rows[] = array(
    'Table data value',
  );
  return theme('table', array('header' =&gt; $header, 'rows'=&gt; $rows));
}
