Skip starting blank rows in Excel with XLSX in JavaScript Sheet-JS

I have the following code that works great when the header row is row 1

  readerData(rawFile) {         
      return new Promise((resolve, reject) => {
        const reader = new FileReader();
        reader.onload = e => {
          const data = e.target.result;
          const workbook = XLSX.read(data, { type: "array" });
          const firstSheetName = workbook.SheetNames[0];
          const worksheet = workbook.Sheets[firstSheetName];
          const header = this.getHeaderRow(worksheet);
          const results = XLSX.utils.sheet_to_json(worksheet,{ header: 0, range: 0, defval: ""});
          this.generateData({ header, results });
          this.loading = false;
          resolve();
        };
        reader.readAsArrayBuffer(rawFile);
      });
    },
    generateData({ header, results }) {
      this.excelData.header = header;
      this.excelData.results = results;
      this.excelData.original_results = [...results];
      this.onSuccess && this.onSuccess(this.excelData);

         var grid = this.$refs.membersGrid.ej2Instances;                         
        grid.dataSource = this.excelData.results;
          grid.refresh(); 
    },
      getHeaderRow(sheet) {
      const headers = [];
      const range = XLSX.utils.decode_range(sheet["!ref"]);
      let C;
      const R = range.s.r;
      /* start in the first row */
      for (C = range.s.c; C <= range.e.c; ++C) {
        /* walk every column in the range */
        const cell = sheet[XLSX.utils.encode_cell({ c: C, r: R })];
        /* find the cell in the first row */
        let hdr = "UNKNOWN " + C; // <-- replace with your desired default
        if (cell && cell.t) hdr = XLSX.utils.format_cell(cell);
        headers.push(hdr);
      }
      return headers;
    },

It works great and put all of the Header values into the excelData.header and it put all of the named array data into the excelData.results. My problem is it all goes to a mess when the first row or first two rows are blank or I need to skip them. I’ve tried

  https://github.com/SheetJS/sheetjs/issues/463

but I’m using “xlsx”: “^0.17.1” . When I used

    range.s.r = 1;

I was able to change my range to A2 but I could not get my named array of data. Any help is appreciated .
