If you would like to add more datasheets to the comparison table you can still find and add them around the site while browsing, querying or searching OS Specs. Meanwhile you will not lose the comparison table below. Furthermore unnecassary datasheets can be removed by clicking on the "Remove from comparison" buttons (ever more than one item during one page load) but in this case reloading the table will be needed. Then click again on the appropriate header "Compare" button.
