Add support for MorphOne relationships

[DanielGSoftware]

Take the following relationship
Model Address, which has a morphTo() method and has addressable_id and addressable_type columns.
Model User , which has MorphOne() that points to the address model.

If I have a user table, and I want to display the street of the address, I would do Column::make('street', 'address.street').

This will give the following exception: Rappasoft\LaravelLivewireTables\Views\Column::setTable(): Argument #1 ($table) must be of type string, null given, called in /Users/danielgebben/Documents/LenderSpender/platform/vendor/rappasoft/laravel-livewire-tables/src/Traits/Helpers/ColumnHelpers.php on line 24.

This is because MorphOne is not supported when making the columns.

Reopen, I still think this is relevant.

[hasan-ozbey]

[Francesco-Cirillo]

thank you for the change.
I need it in my web project, but I don't want to edit my vendor directory: I have to wait he pull request will be accepted?

Just manually applied the small changes to test and it works flawlessly! Thanks @DanielGSoftware! ❤️

@rappasoft What is necessary for this to be merged?

Edit: Actually, whilst it does solve the error and retrieves the data, the sorting itself doesn't seem to work
Edit2: I've created an issue ( #987 ) that potentially found the issue for the sorting problem

For anyone finding this, you can (as temporary solution) copy the version from this Pull Request into a new file.
For example: App\Traits\WithData. Make sure to change the namespace at the top to: namespace App\Traits;

Then go to the AppServiceProvider and add the following line as imports:

use Rappasoft\LaravelLivewireTables\Traits\WithData;
use App\Traits\WithData as WithDataFixedUnsupportedMorph;

And add the following in the register function:

$loader = AliasLoader::getInstance();
$loader->alias(WithData::class, WithDataFixedUnsupportedMorph::class);

Tested against core, all appears working @rappasoft - this seems okay to commit
