Call to undefined method BooleanColumn::format()

[sheepbild]

Hi,

in the documentation you mentionned the code below : BooleanColumn::name('email_verified_at') ->label('Email Verified') ->format() ->filterable(), But the format() function throw me an error "Call to undefined method Mediconesystems\LivewireDatatables\BooleanColumn::format()" and no format() function is present in the Column.php file.

What is this function for, is it important ?

Thank you for your super package !
