用js将表格从html导出到excel (方向问题)

function exportToExcel() {
  // 获取表格对象
  var table = document.getElementById("myTable");

  // 创建一个Workbook对象
  var workbook = XLSX.utils.book_new();

  // 创建一个Worksheet对象
  var worksheet = XLSX.utils.table_to_sheet(table);

  // 将Worksheet对象添加到Workbook对象中
  XLSX.utils.book_append_sheet(workbook, worksheet, "Sheet1");

  // 将Workbook对象转换为二进制数据
  var excelData = XLSX.write(workbook, { bookType: "xlsx", type: "array" });

  // 创建一个Blob对象，并生成下载链接
  var blob = new Blob([excelData], { type: "application/octet-stream" });
  var url = URL.createObjectURL(blob);

  // 创建一个a标签，并设置下载链接
  var a = document.createElement("a");
  a.href = url;
  a.download = "table.xlsx";

  // 模拟点击a标签进行下载
  a.click();

  // 释放URL对象
  URL.revokeObjectURL(url);
}
