Add jQuery Datatables in magento 2

You can add jquery with your script in template file no need to add dependency in reuirejs-config.js

I have put my script here please try this.

<script type="text/javascript">
require(['jquery', 'DataTable'],function($){
    (function() {
         $('#relatedProductTable').DataTable({
              "aaData":<?php echo json_encode($dataProducts);?>,
              "aoColumnDefs":[{
                    "sTitle":"Site name"
                  , "aTargets": [ "site_name" ]
              }]);
                    })(jQuery);
});

I think that you have another problem in your script. you have defined both jquery and datatable as dependencies. But you only pass jquery to the function. The function part of the requirejs script should have the dependency scripts object passed to the function part. try:

<script type="application/javascript">
requirejs(['jquery','dataTable'],function($, dataTable){
    $(document).ready(function(){
        $('#list-table').DataTable();
    });
});

As for the shim part, I think that if you have defined it something like :

var config = {
    map: {
        '*': {
            dataTable: 'Ktpl_Slider/js/datatables.min'
        }
    },
    "shim" {
        "dataTable" : ["jquery"]
    }
};

then it's fine. Looks like it works for me, however, the extra quotes around "shim" are only present in Magento 2 documentation, and not in requirejs documentation. so not sure which one is right.
