Is there another way to display export button in Yajra datatable using laravel 5.8?

I'm using YajraDatatables to query a list of users on the server side. I added all dependencies but the button is not showing. Buttons are Copy, PDF, CSV, and even display custom buttons. I've tried using different versions of JQuery but still no results. When I just initialize the datatable with the data array from the view, the buttons show up and work fine, but when I add the datasource from the route and server side, the buttons don't show up. Is something missing? Below is my server side processing code, the button is not shown. I didn’t collect it when debugging.

I want to first perform a query limited to 3 records, and then sort the results of this query by a column called ContactName. I think this might be a nested query. Nested queries run fine in SQLServer, but don't know how to implement it in MySQL. Limit query: Select*fromcustomerslimit

Copy using jQuery Clone

Course Introduction：I recently played a guest role on the front end, and the row copy function was implemented using jQuery. It feels much simpler than using CreateElement with native js before, but I still encountered some traps such as IE7 bugs, which are recorded here. Let’s take a look at what the table looks like: here are three rows in a group. Press Copy to copy the values, and press Add to only add rows without copying values. The calendar uses the datepicker in jQuery UI. The picture below is just a simple demo without a complicated style sheet.
