columns.render does not work

Hello,
I am using Datatables with server side precessing. My goal is to have a column which uses several properties of my data source to assemble each cell html. At first I though of setting the option columns.render to a function, and columns.data to null, in accordance to their specifications.
However, regardless of the value I pass to columns.data, it doesn't seem to work, and I get that warning saying that the parameter is unknown. Odd enough, if I set columns.defaultContent, the warning goes away, but I get stuck with a fixed value for all the column's cells.
I was able to reproduce this issue in a plunkr

Could it be that the documentation is outdated and I am passing an invalid combination of options?
It would be great to find out what the problem is.

Changed from using
columnDefstocolumnssimply because you are configuring each column individually andcolumnstakes precedence overcolumnDefs. Also note I removed thetargetsoption as that is not used withcolumns. However you can stick with your columnDefs and it will still work with the following two changes.In your last column I made the following changes:
"data": null,and addeddefaultContent: '',returnstatement. Apparently Javascript does not recognize the string if it starts on the next line.Kevin
