We need to . If we use splitAt() method to lock the columns, we are getting js error. In the documentation, it has been mentioned that �this mode is incompatible with some grid functionality�. Can you please let us know how to incorporate this functionality?
split is really can be incompatible with some other functionality but in nearly never resulted in direct JS errors.
Please be sure that you call splitAt after all structure initialized and grid.init() called, but before data loaded in grid
If problem still occurs for you - please provide any kind of sample where it can be reconstructed.
