You can tweak the way it looks through the stylesheet. How did you manage to do the blue background because I'm not seeing it in your stylesheet.
To move it up the page you have to actually move the chunk of code in that file to the appropriate spot.
Open this file: /includes/templates/template_default/templates/tpl_product_info_display.php
Take this chunk of code from the lower section:
<!--bof Quantity Discounts table -->
<?php
if ($products_discount_type != 0) { ?>
<?php
/**
* display the products quantity discount
*/
require($template->get_template_dir('/tpl_modules_products_quantity_discounts.php',DIR_WS_TEMPLATE, $current_page_base,'templates'). '/tpl_modules_products_quantity_discounts.php'); ?>
<?php
}
?>
<!--eof Quantity Discounts table -->
Copy it. Delete it. Go up above and paste it where you want it. Personally I think it looks best right under the product price block.
Now copy the file back onto your server. But make sure to use the ovverrides and drop it here: /includes/templates/CUSTOM/templates/tpl_product_info_display.php
instead of here: /includes/templates/template_default/templates/tpl_product_info_display.php
Even if that means you have to make those folders. Obviously change CUSTOM to your custom template name.
Also, I would get rid of the blue thick outline. It is a bit.. jarring. People will see the table once you move it.
