Any idea how to add a third row?

In the documentation there is a method called "description" but I need another row

I need something like this

Solution

You could probably just add a line break by returning an HtmlString ...

TextColumn::make('foo')
  ->description(fn (Model $record): string => new HtmlString($record->thing1 . '<br>' . $record->thing2)),

TextColumn::make('foo')
  ->description(fn (Model $record): string => new HtmlString($record->thing1 . '<br>' . $record->thing2)),
