I am using this code to expand the rows:
which generates the result shown on image 1, which is absolutely correct.
When I wrote this code to expand the columns:
you can see the result on image2 attached. As I've wrote in my question, the colspan that generated is all wrong, you can see in the image that the months are not aligned at all with the grid content. How can I fix this?
Also, which verson of the jquery.min.all.js is the most recent? I just download the kendo ui and it came with the v2015.2.624, but on a dojo demo I found a v2015.5.805, which corrects some of the bugs that I have had with expanding columns. Which one should I use and is the most recent?
