Is there a way to automatically validate data before it is displayed in Yajra DataTables for Laravel 11

1. Modify the DataTable Class:
In your DataTable class (e.g., `UsersDataTable`), you can override the `with()` method to apply validation rules to the query:

php
public function with($query)
{
    return $query->validate([
        'name' => 'required|string|max:255',
        'email' => 'required|email|max:255',
    ]);
}

In this example, we're applying validation rules to the `name` and `email` columns. You can add more validation rules as needed for your specific columns.

2. Handle Validation Errors:
If there are any validation errors, you can handle them in the DataTable class by overriding the `ajax()` method:

php
public function ajax()
{
    return $this->dataTable()
        ->toJson();
}

public function dataTable($query)
{
    return $this->applyScopes($query)
        ->validateWithBag('datatable')
        ->toJson();
}

In this example, we're using the `validateWithBag()` method to apply the validation rules and store any errors in the `'datatable'` validation bag.

3. Display Validation Errors in the View:
In your view, you can display the validation errors using the `$errors` variable:

html
@if ($errors->hasBag('datatable'))
    <div class="alert alert-danger">
        <ul>
            @foreach ($errors->getBag('datatable')->all() as $error)
                <li>{{ $error }}</li>
            @endforeach
        </ul>
    </div>
@endif

<table class="table table-bordered data-table">
    <!-- Table content -->
</table>

In this example, we're checking if there are any validation errors in the `'datatable'` validation bag and displaying them in an alert message.

By following these steps, you can automatically validate data before it is displayed in Yajra DataTables for your Laravel 11 application. The package provides a flexible API for applying validation rules to the DataTable queries and handling any validation errors that may occur.
