Botao Limpar

Olá a todos, gostaria de uma ajuda.

Tenho um gerador de tópicos para o meu site no qual tenho o seguinte trecho:

Neste trecho tenho a variável link[] 6 vezes que depois eu processo em um código php, o meu drama é, queria criar um botão que limpasse somente o conteúdo que foi digitado nestes campos link[] que são um textarea

Tentei de varias formas mas não consegui, se alguém puder me ajudar...

Supondo que a tabela que você postou tenha um ID (se não tiver, coloque algum).

function limpaAreas() {
    var areas = document.getElementById('id_da_tabela').getElementsByTagName('textarea');
    for (var i = 0; i < areas.length; i++) {
        areas[i].value = '';
    }
}

<input type='button' value='limpa' onclick='limpaAreas()'/>
