问题
I am initilizing a grid that contains more than a few thousand columns. The columns are defined by a user of my system and there is no limit to what they can define.
The performance is extremely slow. Approximately 5 minutes for the grid to render. Is there an alternative that I can do to enhance the rendering of the table?
It appears as though the columns go through a method called recursivelyCreateColumns which in my case gets called thousands of times.
Any help is appreciated
