I'm adding hasScopes method to check if the current DataTable class has the given scopes.
In my case, I have to determine the columns based on scopes. For example, it the DataTable class has a scope then I need to display A, B and C, otherwise display only A and B.

/**
 * Get columns.
 *
 * @return array
 */
protected function getColumns(): array
{
 $columns = [
 'A',
 'B',
 ];
 if ($this->hasScopes([MyScope::class])) {
 $columns = array_merge(
 $columns,
 [
 'C'
 ]
 );
 }
 return $columns;
}

I'm also adding a second parameter to the hasScopes method, it's a boolean flag (false by default) to set whether to check all the values for true, or to return true if at least one class is matched.

$this->hasScopes([FirstScope::class, SecondScope::class], true)

If we pas the second parameter true, we will check all the given query scopes for true, it means the DataTable class should have FirstScope and SecondScope class.
