This is how I ended up combining Vue and DataTables. Both want to control the DOM, which will not work.

There some good content here: vuejs/vue#423

For my use case all I wanted from Vue was the power to easily render a <table> and then hand it over to DataTables and get out of the way. The strategy was to use a v-for that iterated on variable that didn't have all the "observable" stuff hooked to it.

This tip from Evan You showed how to use the created hook to create variables that will not have the observable machinery hooked to it, but is still accessible as a variable within the Vue component. Which means you can iterate on it with a v-for.

So what you end up with is a table rendered once by Vue, and then you pass that table on to the DataTables lib, and they will never interact with one another.

As for modifying the data table, I used the DataTables way of changing the data. My example did a delete only. I'm sure an add could be performed in a similar manner.

Also, my example was reading data from a server. Adapt as you wish.

Caveat emptor -- I copied and pasted working code, then edited out a bunch of stuff to make it generic, removed irrelevant stuff, made up a few functions just to convey the idea. But the code in the gist has not been tested. So you might find a typo or two. It's just to convey the idea.

Not working for me :((
it keeps complaining about datatable function is not there:

TypeError: $(...).DataTable is not a function

here is my component code.

Thanks in advance.

    console.log($(id));
    debugger; // <-- maybe stop here and have a look at things from the console to see why .DataTable() is not there...
    this.datatable = $(id).DataTable({
      ordering: false
    });

Does $(id) return the element okay and print it where you did your console log?

If yes, then jQuery is working, and it would seem that the DataTable lib is not loading correctly with jQuery. ??

Thanks!

Yes, it behave as expected.
I even checked if it brings the datatable from the remote server and it looks fine, I also checked (n times) the script load order.
