How to make the matrix element output several fields as default?

[AlexanderKhq]

Hello. I want to output 2 columns and 3 rows of input-type-text in the matrix element as default(after pages has loaded). I don't get how to do that. I output 2 columns and no rows as default. Can anyone help me?

I've tried this:
Matrix::make('Categories') ->title('категроии:') ->columns([ 'Раздел:' => 'wp_name', 'Ключевые слова:' => 'pattern' ])->fields([ 'wp_name' => Input::make('wp_name')->type('text'), 'pattern' => Input::make('pattern')->type('text'), 'wp_name1' => Input::make('wp_name')->type('text'), 'pattern2' => Input::make('pattern')->type('text') ]),
