background-color: green !important;
font-weight: bold;
}
.highlightTableRowRed {
background-color: red !important;
font-weight: bold;
}

<p:dataTable id="articleTable" value="#{articleCtr.listArticle}" var="article" rowKey="#{article.num_article}"
selection="#{articleCtr.selectedArticle}" selectionMode="single" rowStyleClass="#{(article.quantity) lt 10 ? 'highlightTableRowGreen': null}">
