How my I use the additional column types?

From a previous question that I found in the Knowledge Base:
> There are some more additional eXcell types can be
distributed, based on package version
(“acheck”,“mro”,“ed_text”,“cntr”) - but
they have very specific functionality.

I liked the example that uses acheck .  We are paying for the Professional version.  Will you please tell me how I can use acheck?  Also could you please describe the others (“mro”,“ed_text”,“cntr”)?



To use some additional excell type - you need to include related js file
    in case of “acheck” - excells/dhtmlxgrid_excell_acheck.js
and use it “acheck” as column type in
    grid.setColTypes command
