The documentation for how to read information from objects is available here.

For example you could use: data: 'user.loginname' for a column to display the login name.

I try to use data: 'user.loginname' for a column
but it causes a bug when I attempt to order table by loginname
:the condition which was send to backend is "'user.loginname'rather than loginname

allan

Yes - your server-side processing script, whatever that is, would need to be able to accept data in that form. The simple fact is that there is no parameter called loginname at the top level of the data object, which is why you need to use the nested data form to tell DataTables where to get it.
