Table column ordering

To address the issue of preserving the custom ordering of your column in Filament, you need to ensure that the sorting logic is correctly applied both in your MySQL view and in the Filament model. Here’s a step-by-step solution:

1. Custom Sorting in MySQL View: Ensure that your MySQL view sorts the column in the desired order. You can use a combination of ORDER BY and custom sorting logic to achieve this. For example:

   CREATE VIEW sorted_view AS
   SELECT *
   FROM your_table
   ORDER BY
     CASE
       WHEN column REGEXP '^[0-9]+$' THEN LPAD(column, 10, '0')
       WHEN column REGEXP '^C[0-9]+$' THEN LPAD(SUBSTRING(column, 2), 10, '0')
     END;
   

   This SQL snippet ensures that numeric values are zero-padded to maintain proper order and that values starting with 'C' are also sorted correctly.

2. Custom Sorting in Filament: In your Filament model, you need to ensure that the custom sorting logic is applied when fetching data. You can achieve this by overriding the default query used by Filament. Here’s an example in a Filament resource:

   namespace App\Filament\Resources;
   
   use Filament\Resources\Resource;
   use Filament\Resources\Table;
   use Filament\Tables;
   use App\Models\YourModel;
   
   class YourModelResource extends Resource
   {
       protected static string $model = YourModel::class;
   
       public static function table(Table $table): Table
       {
           return $table
               ->columns([
                   Tables\Columns\TextColumn::make('column_name')
                       ->label('Column Name'),
                   // Add other columns as needed
               ])
               ->defaultSort('column_name', 'asc')
               ->query(function ($query) {
                   $query->orderByRaw("
                       CASE
                           WHEN column_name REGEXP '^[0-9]+$' THEN LPAD(column_name, 10, '0')
                           WHEN column_name REGEXP '^C[0-9]+$' THEN LPAD(SUBSTRING(column_name, 2), 10, '0')
                       END
                   ");
               });
       }
   }
   

   In this example, the orderByRaw method is used to apply the same custom sorting logic as in the MySQL view.

By ensuring that both your MySQL view and Filament model apply the same sorting logic, you can preserve the desired order of your column when displaying it in Filament.
