Class Divider

分隔线

水平分隔线。如需向附加卡片添加分隔线，请在 CardService 中使用 newDivider() 方法。例如，以下示例构建了一个由分隔符分隔的 2 个段落组成的简单卡片。 

function buildCard() {
  const cardSection1TextParagraph1 =
      CardService.newTextParagraph().setText('Hello world!');

  const cardSection1Divider1 = CardService.newDivider();

  const cardSection1TextParagraph2 =
      CardService.newTextParagraph().setText('Hello world!');

  const cardSection1 = CardService.newCardSection()
                           .addWidget(cardSection1TextParagraph1)
                           .addWidget(cardSection1Divider1)
                           .addWidget(cardSection1TextParagraph2);

  const card = CardService.newCardBuilder().addSection(cardSection1).build();

  return card;
}
