在 primeng 数据表中导出 pdf 在 Angular 9 中不起作用

Export pdf in primeng datatable is not working in Angular 9

我尝试在 Angular9 的 Primeng 数据表中实现导出为 PDF。我的代码如下:

exportPdf() {
  this.cols = [
    { field: 'code', header: 'Code' },
    { field: 'name', header: 'Name' },
    { field: 'category', header: 'Category' },
    { field: 'quantity', header: 'Quantity' }
];

this.exportColumns = this.cols.map(col => ({title: col.header, dataKey: col.field})); console.log(this.exportColumns)
import("jspdf").then(jsPDF => {
  import("jspdf-autotable").then(x => {
      const doc = new jsPDF.default(0,0);
      doc.autoTable(this.exportColumns, this.products);
      doc.save('products.pdf');
      
 })
})
}

但是我收到这个错误:

error TS2345: Argument of type '0' is not assignable to parameter of type 'string'.

    in       const doc = new jsPDF.default(0,0);

我还安装了这些:

"jspdf": "^1.5.3",
"jspdf-autotable": "^3.5.13"

我该如何解决这个错误。有人可以帮我吗?

默认方法将第一个参数作为字符串 '"p" | "portrait" | "l" | "landscape"',第二个参数是单位并采用这些值 "pt" | "px" | "in" | "mm" | "cm" | "ex" | "em" | "pc"

import jsPDF from "jspdf";
import "jspdf-autotable";
...

exportPdf() {
    const doc = new jsPDF('p','pt'); // or like this  new jsPDF();
    doc.autoTable(this.exportColumns, this.products);
    doc.save("products.pdf");
}
