Is it possible to define a custom column property. eg. I might have a set of columns that I need to arbitrarily group together to set a css style on, where this cannot be achieved by identifying those columns using any of the other column properties.

This might look something like

$col[“coltype”] = “custom”

$col[“customrule”]=”CSS type 1″

This way I would be able to set css styles based on an arbitrary grouping of columns within the grid.
