Run php artisan vendor/publish command to publish the views contained in the package.
The class contains 2 methods - sort() and sortSearch(). Both take different params. The methods return simple templates used to form the column name link with the necessary parameters. Since those parameters are presented in the Laravel request object, you can use them to construct you database query.
For example you can use in your template
First argument is your get page controller method. Second argument is the text that should be shown as column name in the table. Third argument is the database table column name or alias from which the data is coming. Fourth one is the sorting direction. This can be provided as variable since it is determined by the module itself. Last argument is used to represent items per page number, in case you are using pagination.
The other method provided by the module can be used to sort search results.
