The issue occurrs when in the data objects array there are objects without any property instantiated (here it is your sample modified: https://jsfiddle.net/dh2fwx1a - note the data objects array). When I try to order column C, the rows related to the void cells stand in the initial position and aren't ordered as last rows of the table. if you had problems to execute my demo, try to run the link without the last \"/\": https://jsfiddle.net/xjqoh2z0  (it works for me)."}}
