Representation of cart block,

Hello,

perhaps it is of interest to represent the block so?
From line # 187 in uc_cart.theme.inc

// Build the basic table with the number of items in the cart and total.
  $output = '<table class="cart-block-summary"><tbody><tr>'
           . '<td class="cart-block-summary-items">' . $item_text . '</td></tr>'
           . '<tr><td class="cart-block-summary-total"><label>' . t('Total:')
           . '</label> ' . theme('uc_price', array('price' => $total)) . '</td></tr>';

  // If there are products in the cart...
  if ($item_count > 0) {
    // Add a view cart link.
   <em> $output .= '<tr class="cart-block-summary-links"><td>'</em>
             . theme('links', array('links' => $summary_links)) . '</td></tr>';
  }

  $output .= '</tbody></table>';

  return $output;
}

your code:

 // Build the basic table with the number of items in the cart and total.
  $output = '<table class="cart-block-summary"><tbody><tr>'
           . '<td class="cart-block-summary-items">' . $item_text . '</td>'
           . '<td class="cart-block-summary-total"><label>' . t('Total:')
           . '</label> ' . theme('uc_price', array('price' => $total)) . '</td></tr>';

  // If there are products in the cart...
  if ($item_count > 0) {
    // Add a view cart link.
   <em> $output .= '<tr class="cart-block-summary-links"><td colspan="2">'</em>
             . theme('links', array('links' => $summary_links)) . '</td></tr>';
  }

  $output .= '</tbody></table>';

  return $output;
}
