我正在尝试使用 jsPdf Auto-table 将动态数据打印到 pdf 文件中。当我这样做时，我遇到了某种错误，比如

The headers should be an object or array, is: function     (jspdf.plugin.autotable.js:10 )
The data should be an object or array, is: function        (jspdf.plugin.autotable.js:10)
TypeError: t.forEach is not a function     (angular.js:12314)

这是我的代码 -

var getColumns = function () {
    return [
        { title: "ID", dataKey: "id" },
        { title: "Name", dataKey: "first_name" },
        { title: "Email", dataKey: "email" },
        { title: "City", dataKey: "city" },
        { title: "Country", dataKey: "country" },
        { title: "Expenses", dataKey: "expenses" }
    ];
};

function getData(mainSteps) {
    mainSteps = mainSteps || 4;
    //var sentence = faker.lorem.words(12);
    var data = [];
    for (var j = 1; j <= rowCount; j++) {
        data.push({
            id: j,
            first_name: this.getSteps(),
            email: this.getSteps(),
            country: this.getSteps(),
            city: this.getSteps()(),
            expenses: this.getSteps()
            // text: shuffleSentence(sentence),
            //text2: shuffleSentence(sentence)
        });
    }
    return data;
}

var pdfsize = 'a4';
var doc = new jsPDF('p', 'pt', pdfsize);

doc.autoTable(getColumns, getData, {
    theme: 'grid', // 'striped', 'grid' or 'plain'
    headerStyles: {
        fillColor: [12, 234, 227],
        textColor: [12, 1, 1]
    },
    // margin: { top: 50, left: 20, right: 20, bottom: 0 },
    styles: {
        overflow: 'linebreak',
        columnWidth: 88
    },
    beforePageContent: function (data) {

        doc.text("Process Name :" + mainData.name + "  ||   " + "Description :" + mainData.description, 40, 30);

    },
    //startY: doc.autoTableEndPosY() + 20,
    columnStyles: {
        0: { columnWidth: 200 }
    }
});

//startY: doc.autoTableEndPosY() + 20
doc.save(mainData.name + ".pdf");

注意：如果错误在我的代码中意味着我可以找到解决方案，但它说错误在 (jspdf.plugin.autotable.js:10 )和(angular.js:12314) 中，所以我在这里感到困惑。有人可以澄清一下吗？

正如错误所解释的，输入数据必须是数组或对象。在您的情况下，这仅意味着调用函数而不是将它们发送到 autotable。替换这个

doc.autoTable(getColumns, getData, {...});

和

doc.autoTable(getColumns(), getData(), {...});
