在pdfmake上关联另一个数组的列

var mainData = [
  { id: 1, name: "John", city: "New York" },
  { id: 2, name: "Jane", city: "London" },
  { id: 3, name: "Tom", city: "Tokyo" }
];

var associatedData = [
  { id: 1, occupation: "Engineer" },
  { id: 2, occupation: "Designer" },
  { id: 3, occupation: "Teacher" }
];

var docDefinition = {
  content: [
    {
      table: {
        body: [
          ["ID", "Name", "City", "Occupation"],
          // Iterate over the main data array
          ...mainData.map(data => {
            // Find the associated data for the current main data
            var associated = associatedData.find(item => item.id === data.id);
            return [data.id, data.name, data.city, associated.occupation];
          })
        ]
      }
    }
  ]
};

// Generate the PDF document
var pdfDocGenerator = pdfMake.createPdf(docDefinition);
pdfDocGenerator.download("example.pdf");
