您将必须遍历每个数组中的每个值，并为每个数组创建一个段落小部件。

function notifyNo(array1,array2,array3)
{
    var highRiskDomains = CardService.newCardSection().setHeader('<b><font color="#FF0000">High-Risk Domains</font></b>');
    array3.forEach(function(value)
    {
        highRiskDomains.addWidget(CardService.newTextParagraph().setText('<font color="#FF0000">' + value + '</font>'));
    });

    var lowRiskDomains = CardService.newCardSection().setHeader('<b><font color="#CCCC00">Low-Risk Domains</font></b>');
    array2.forEach(function(value)
    {
        lowRiskDomains.addWidget(CardService.newTextParagraph().setText('<font color="#CCCC00">' + value + '</font>'));
    });

    var safeDomains = CardService.newCardSection().setHeader('<b><font color="#006400">Safe Domains</font></b>');
    array1.forEach(function(value)
    {
        safeDomains.addWidget(CardService.newTextParagraph().setText('<font color="#006400">' + value + '</font>'));
    });

    return CardService
        .newCardBuilder()
        .setHeader(
            CardService.newCardHeader()
                .setTitle('Draft Validation Check')
                .setSubtitle("Please validate the below recipients before sending out this message")
                .setImageStyle(CardService.ImageStyle.SQUARE)
                .setImageUrl('https://i.imgur.com/4uNXq15.png')
        )
        .addSection(highRiskDomains)
        .addSection(lowRiskDomains)
        .addSection(safeDomains)
        .build();
}
