If you are meaning something similar to this wsith the $ and the decimal points lined up.

Code:
Small:         [ ] CANVAS 18.0" x 14.0"   $ 20.00 USD

Medium:        [ ] CANVAS 24.0" x 20.0"   $ 40.00 USD

Large:         [ ] CANVAS 30.0" x 24.0"   $ 60.00 USD

Extra Large:   [ ] CANVAS 38.0" x 24.0"   $110.00 USD
Then tables are not going to net you this as the entry like CANVAS 38.0" x 24.0" $110.00 USD is all one assembled item. One would have to rip the code apart and as these are attributes and if you can dicipher the code start with tpl_ and anything to do with attributes and the tpl_product_info_display.php file
