I'm not sure what you meant by drag and drop on a column? Would you like to drag some blocks to a cell in a table?
For my personal knowledge, we currently do not have that kind of function in the form builder by default. Although, we do have a couple of widgets that might be of use to you, you can check our widgets page here: http://widgets.jotform.com/.
I hope this helps.
