Set column in mobile interface

We’ve added DT Product Category and DT Product Tabs into frontpage. and set column to 4. It works well on PC interface.
However, there is no option to set column in mobile interface. It shows as single column in mobile interface by default.

We prefer to set column to 2 in mobile interface.
In there any quick fix or walkaround to do that?

Thanks a lot!!
Harrison
