I'm trying to understand the interface for server side processing, but I just can't follow the documentation. I'm trying to understand the sent parameters, but I'm lost. Looking at the documentation here:
https://datatables.net/manual/server-side
I understand things like start, and length. I expect that those will translate to an URL of the form:
http://localhost:9000/v2/egenes/Whole_Blood?draw=1&start=0&length=10
That is clear. But I'm completely lost when it comes to the "columns[i]" fields. What in the heck are these? Can someone provide me with a concrete example showing what is sent to the server? I've looked at the example here:
https://datatables.net/examples/server_side/simple.html#
but I just can't figure out what is sent to the server.
