Pdf 邮件范围不是整个工作表-应用程序脚本

我有一张谷歌表格。我想把它以PDF格式发送出去。 下面的代码可以将整个表单（一个选项卡）以pdf格式发送电子邮件。 &范围不起任何作用。我想要它，但它没有。 问题：如何更改此代码，使其发送电子邮件给“选定单元格”？ 附加问题：为什么我必须输入？exportFormat=pdf和&format=pdf

      var url_base = ss.getUrl().replace(/edit$/,'');
      var url_ext = 'export?exportFormat=pdf&format=pdf'   //export as pdf
      + (sheetId ? ('&gid=' + sheetId) : ('&id=' + ssId))
      + '&range=E1:L25' // <<< THIS DOESN'T SEEM TO DO ANYTHING
      + '&format=pdf'                   //export format

var url\u base=ss.getUrl（）.replace（/edit$/，“”）；
var url_ext='export？exportFormat=pdf&format=pdf'//导出为pdf
+（sheetId？（'&gid='+sheetId）：（'&id='+ssId））
+“&range=E1:L25”/实际上它确实有效。找到用作基础的源代码的原始定义后，我发现我将参数设置为通过电子邮件发送整个Sheets文件，而不是一个选项卡。指向一个选项卡后，&range参数被激活，我得到了所需的结果

电子邮件工作簿或选项卡参考：

还有我自己的扩展，包括射程能力和其他一些改进

/*
shNum = 0 for whole workbook or '0', or 0,1,2,etc for specific tab/sheet
shRng = A1 address for desired range, eg 'E1:L25', ignored if not a single sheet shNum
pdfName = text on top of pdf
*/
function mailPdf(shNum,shRng,pdfName,email,subject,htmlbody) {
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var ssId = ss.getId();
  var shId = shNum ? ss.getSheets()[shNum].getSheetId() : null;  
  var url_base = ss.getUrl().replace(/edit$/,'');
  var url_ext = 'export?exportFormat=pdf&format=pdf'   //export as pdf
      + (shId ? ('&gid=' + shId) : ('&id=' + ssId))
      + (shRng ? ('&range=E1:L25') : null)

  var options = {
    headers: {
      'Authorization': 'Bearer ' +  ScriptApp.getOAuthToken(),
      'muteHttpExceptions': true
    }
  }

  var response = UrlFetchApp.fetch(url_base + url_ext, options);
  var blob = response.getBlob().setName(pdfName + '.pdf');
  if (email) {
    var mailOptions = {
      attachments:blob, htmlBody:htmlbody
    }


MailApp.sendEmail(
      // email + "," + Session.getActiveUser().getEmail() // use this to email self and others
      email,                                              // use this to only email users requested
      subject+' (' + pdfName +')', 
      'html content only', 
      mailOptions);

  }
}

你好您将如何动态设置范围？
