Attach renderer to column after initialization?

Martin@heco

I have a datatable, which is recieving the column data and definition from a webservice. Some columns may exist or may not exist, depending on the webservice data provided. Specific columns should be rendered in a different way, so I've written a renderer for those.

However, I would only like to use these render functions for specific columns (in my example I need to insert a link into all cells of this column). To keep frontend and backend separated, I do not want to decide the rendering in the backend webservice, but in the frontend.

Is it possible to attach a render function to a specific column after initialization? Something along this pseudocode

// ... webservice call outside of datatable into xhrData ...
var api = $("#example").DataTable(
    "columns": xhrData.columns,
    "data": xhrData.data,
    // ...);

if (api.column("price:name") != undefined) {
    api.column("price:name").render(function (a, b, c, d) {
        // ... do magic ...
        return changedResult;
    });
}

No - sorry. This is not something that can be defined after initialisation.

You would need to loop over xhrData.columns before you initialise the table and add the rendering methods as needed there.
