I want to know is there any way to have a row number (NOT ID) just beside the ID
field on the resource pages?
Here is the solution I found based on Origami1024 's answer, his/her answer just supports the first page and does not consider the pagination pages. Here is the solution based on his/her answer:
public function fields(Request $request)
{
if (!$request->count) {
$request->count = 0;
}
return [
Text::make('#', function () use ($request) {
$request->count += 1;
$rowNumber = $request->page == 1 ? $request->count : $request->count + ($request->perPage * ($request->page - 1));
return $rowNumber;
})->onlyOnIndex(),
ID::make()->sortable(true),
Text::make('name'),
...
];
}
