I am aware that this method is available on the pro-version but was wondering if will work in the below case.

I have a grid with several columns each having varying col types. When there is data in the grid everything is fine but when the grid is empty and i want to insert a custom message that spans all cells for the one row that I will insert into the grid. If I had access to the enableColSpan(), will it be possible to switch on col spanning to display my text message across the row then turn if off when the user performs action to load the grid before clearing and reloading the grid.

Thanks in advance

You can use setColspan() method to dynamically set colspan in row starting from specified column index. This method is available in PRO version also.
