Javascript 如何导入我在Web Worker创建的函数

我是Web Worker的新手，现在我要做的是导入我在workerCode in Web Worker下创建的函数，但"import"和"importScript"都不起作用；只有XLSX库工作得很好，但其余的都不起作用.

你能帮我弄清楚怎么做吗？

export const consolidateWorkerV2 = () => {
 const workerCode = `
 /* Load standalone script from CDN */
 import * as XLSX from "https://cdn.sheetjs.com/xlsx-0.20.1/package/xlsx.mjs";
 import getDataRange from "../shared/util/GetDataRange";
 import modifyWorksheet from "../shared/util/modifyWorksheet.js";
 import headerStyling from "../shared/util/headerStyling";

 self.addEventListener('message', async (e) => {
  try {
    const files = e.data.files;
    const newWorkbook = XLSX.utils.book_new();
    console.log("message received from main thread");
    for (const [index, item] of files.entries()) {
      const file = item.file;
      const filename = item.file.name
      const data = await item.file.arrayBuffer();
      const workbook = XLSX.read(data);
      
      for (const sheetName of workbook.SheetNames) {
        if (newWorkbook.SheetNames.includes(journalType)) {
          const duplicateSheetName = workbook.SheetNames[0];
          const newWorksheet = newWorkbook.Sheets[journalType];
          const dupWorksheet = getDataRange(workbook.Sheets[duplicateSheetName]);
          const OPTIONS = { raw: false, defval: "", };
          const parsedDupWorksheet = XLSX.utils.sheet_to_json(dupWorksheet, OPTIONS);
          const updatedWorksheet = modifyWorksheet(dupWorksheet, parsedDupWorksheet, duplicateSheetName, journalType, reportDate);
          const newData = updatedWorksheet.map((row) => Object.values(row));
          XLSX.utils.sheet_add_aoa(newWorksheet, newData, { origin: -1, skipHeader: true });
        } else {
          // if no existing sheet name, then add new sheet
          for (const sheetName of workbook.SheetNames) {
            const worksheet = workbook.Sheets[sheetName];
            const worksheetData = getDataRange(worksheet);
            const parsedWorksheet = XLSX.utils.sheet_to_json(worksheet, { raw: false, defval: "", });
            const updatedWorksheet = modifyWorksheet(worksheetData, parsedWorksheet, sheetName, journalType, reportDate);
            const styledSheet = headerStyling(updatedWorksheet);
            XLSX.utils.book_append_sheet(newWorkbook, styledSheet, journalType);
          }
        }
      }
    }
    
    const consolidateFilename = namingConvention("Consolidated_Final_Report", date);
    const excelBuffer = XLSX.write(newWorkbook, { bookType: "xlsx", type: "array", });
    const blob = new File([excelBuffer], fileName + ".xlsx");
    postMessage({ blob: blob });   
  } catch(e) {
    /* Pass the error message back */
    postMessage({ error: String(e.message || e).bold() });
  }
}, false);
`;

  const blob = new Blob([workerCode], { type: "text/javascript" });
  const worker = new Worker(URL.createObjectURL(blob), { type: "module" });
  return worker;
};
