[ Percent ](https://laravel-datatables.com/docs/formatter-percent) Value Preparation ================= Value preparation lets you transform a column value before formatter and renderer logic runs. Using prepare() --------------- Prepare callbacks always run, even when no formatter is defined. The prepared result replaces the original value for the rest of the pipeline. Prepare with formatter PHP `use App\Support\Datatable\Formatters\PrepareTotalPrice;Column::make('total_price', 'Total Price') ->prepare(new PrepareTotalPrice()) ->format(new \MorrowIt\LaravelDatatable\Formatters\Currency(currencyCol: 'currency'));` ``` use App\Support\Datatable\Formatters\PrepareTotalPrice; Column::make('total_price', 'Total Price') ->prepare(new PrepareTotalPrice()) ->format(new \MorrowIt\LaravelDatatable\Formatters\Currency(currencyCol: 'currency')); ``` Prepare without formatter PHP `Column::make('clean_sku', 'Clean SKU') ->prepare(new \App\Support\Datatable\Formatters\NormalizeSku());` ``` Column::make('clean_sku', 'Clean SKU') ->prepare(new \App\Support\Datatable\Formatters\NormalizeSku()); ``` Use prepare() for normalization and computed values, not for HTML output. Keep visual concerns in renderer classes. How the pipeline works ---------------------- For each cell: 1) prepare callbacks run in order, 2) formatter runs (if defined), 3) renderer runs (if defined). If multiple prepare callbacks are used, ensure each callback receives and returns the expected intermediate type. ### Related Documentation [Row Grouping Features Group rows and create group headers in your datatable for better organization and readability.](https://laravel-datatables.com/docs/feature-row-grouping) © 2026 Copyright (C) [ Morrow IT Consulting & Services ](https://morrow-it.services) [Terms of Service](https://laravel-datatables.com/legal/terms) [Privacy](https://laravel-datatables.com/legal/privacy) [Legal Disclosure](https://laravel-datatables.com/legal/disclosure)
