Sometimes in your tables, you want to show a value that dependes on other model fields, e.g.:
By passing a callback function to the getStateUsing() method from a Column component, you can customize the returned $state value.
Tables\Columns\TextColumn::make('myCalculatedColumn') ->getStateUsing(function(Model $record) { // return whatever you need to show return $record->field1 + $record->field2; })
I'd love to see how to make this Trick also be sortable.
worth noting that you can't rename the callback parameter. it should always be '$record'. or else, the attributes will be empty.
