Google Apps 脚本中二维数组大小的异常错误

如何解决Google Apps 脚本中二维数组大小的异常错误

例外是：

数据中的列数与范围内的列数不匹配。数据为 0，范围为 3。

我想用三列和线程的长度填充谷歌电子表格。当我调试程序时，数组为空。是否应该使用另一种方法来创建可与 getrange 一起使用的二维数组？

function TheaThreads(){
 var SS =SpreadsheetApp.getActiveSpreadsheet();
 var ThreadSheet = SS.getSheetByName("Threads");
 var threads = GmailApp.getInBoxThreads();
 var csNames = new Array();

   for (var i=0; i < threads.length; i++) {
    for (var j = 0; j < 
     threads[i].getMessages().length; j++){
  
     var message = threads[i].getMessages()[j],label = threads[i].getLabels(),ident = message.getId(),emailfrom = message.getFrom();
  
  //remove the name that comes with the email and pops the > at the end and store into str
   
      var str = emailfrom.split("<").pop();
      str=str.replace(">",'');
  // Label empty labels with "No Label"
      if(label==null|| label== undefined|| 
       label.length==0){
       label="No Label";
      }
     }

  //Push the ID,Label and FromEmail into 2D array
  
    csNames[j] = new Array();
    csNames[j][0]= ident;
    csNames[j][1]= label;
    csNames[j][2]=str; 
    Logger.log(csNames[j]);

    ThreadSheet.getRange(2,1,csNames.length,csNames[j].length).setValues(csNames);

解决方法

这对我来说：

 function TheaThreads() {
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var sh = ss.getSheetByName("Sheet1");//changed
  var threads = GmailApp.getInboxThreads();
  var csNames = [['id','label','from']];//changed

  for (var i = 0; i < threads.length; i++) {
    for (var j = 0; j < threads[i].getMessages().length; j++) {
      var message = threads[i].getMessages()[j],label = threads[i].getLabels().map(l=>{return l.getName()}).join(','),ident = message.getId(),emailfrom = message.getFrom();//changed
      var str = emailfrom.split("<").pop();
      str = str.replace(">",'');
      if (label == null || label == undefined ||
        label.length == 0) {
        label = "No Label";
      }
    }
    csNames.push([ident,label,str]);
  }
  sh.getRange(1,1,csNames.length,csNames[0].length).setValues(csNames);//moved
}
