Feature Request: Method callbackClasses()

Hello,

I think it would be good to create a method that allows making a callback to be able to add classes to the parent of the "td".

It would also be good if you can do the same for attributes in case you want to add some "data-xxx" or some other.

In my case I try to put a bg-red when the email is not verified, but in this case it is not possible because it would apply only to the content.

 Column::callback(['id', 'email_verified_at'], function ($id, $email_verified_at) {
      if($email_verified_at == Null) return "<span class='bg-red-500 text-white'>#$id</span>";

      return "<span class='bg-green-500 text-white'>#$id</span>";
      
  })
  ->label('ID'),

<div class="px-6 py-2 whitespace-no-wrap text-sm leading-5 text-gray-900 table-cell  text-left ">
      <span class="bg-red-500 text-white"># 40</span>
  </div>

Expected:

<div class="px-6 py-2 whitespace-no-wrap text-sm leading-5 text-gray-900 table-cell  text-left  bg-red-500 text-white">
      # 40
  </div>

I will try to do it later but in case someone wants to collaborate with a PR I would be grateful.

Thanks ! :D

Start by locating the Column::callback entry point shown in the example and trace how its result is rendered into the table cell. The work is complete when a callback can add classes and custom attributes to the parent td, matching the requested red-cell HTML behavior; no test file is named in the issue.
