Hello,

Working with TreeGrid, found an error that happens when you add several root nodes, studying a lot I found the root of the problem, is in the function “getCol” when we use the value “max” for the parameter “mathopr“

To visualize the problem I uploaded two files, one with the problem and the other with the problem fixed
