If columns are exterior, for instance as part of an exterior colonnade (see example pics here), then model them in the same way cantilevered beams were added as shading surfaces here.
If columns are interior, they should be modelled using the OpenStudio SketchUp Plugin's "New Interior Partition Surface Group" feature (see here) - a step-by-step operation very similar to using the "New Shading Surface Group" feature. As discussed here, interior partition surfaces will reflect/obstruct daylighting when using Radiance.
As with shading, I find it's best to leave a gap (>25mm) between a space's enclosure (e.g. walls, floors), and shading or interior partition surfaces ...
