Create a Newspaper Style Column (Snaking Columns) on output of a PHP based PDF

Hi I have a button that when clicked creates a printable version of our online order form. I'd like to make a change to how it displays the product rows.... Currently the output from the online for looks like this: [login to view URL] The way they would like to have it, looks like Page 7 on this form (made from their Word doc) [login to view URL] I have found lots of links on Google that suggest this is no issue either via php or css. Please help me make this change to my form ASAP. Thank you.
