Hi,
Fairly new to web page programming so forgive my ignorance. I managed to cobble together a working implementation of datatables with buttons a few years ago to show/hide columns and now am trying to upgrade to the latest version. I can no longer get the buttons to show when moving from dom: 'Blfrtip' to layout:. Been playing around in the live environment but having no luck getting it going in there - can anyone see what I'm doing wrong? (I assume the buttons should still show even if they perform no function?)
