how to give a max-length of text?

[guoxiangke]

hi, thanks for this package.
it works fine.
but my text field too long.
before I use this code to add ... and hide.
Text::make(__('Program Description'), 'description')
->rules('required', 'max:255')->displayUsing(function($description) {
return Str::limit($description, 32);
})->onlyOnIndex(),

but now, how to achieve this? thanks.
