Problem with colReorder and render function

trongart

In this test case, I use colReorder and the render function to check what is used for row[0] (please activate the console to see the results). After loading, row[0] is the Name column, but when I move the Name column to the right another column becomes row[0]. How can I keep the same Name column in the render function for row[0] while using colReorder?

I managed to solve it as here with colReorder.transpose

I wonder if this is correct and efficient performance wise.
