column formatter in details pane

for complicated logs, that have a column (or maybe more?) that can contain several properties, I should have a way to format the properties inside the column. 

At a later time, perhaps I could allow complicated filtering based on such columns. 

I should also allow up to ctx30, and properties1-properties10 ("properties" columns)

as an example, it's logs coming from http://cntlm.sourceforge.net/
