数组转置：从＆＃34; Undefined＆＃34;读取属性时出错。

Question

获取以下代码的错误消息，该代码用于从名单为POTemplate的订单输入选项卡中的多个单元格中获取值，并将其记录在我的POHistory选项卡中，用于编译所有订单明细条目的列表。当调试器到达下面代码的底部时，我收到一条错误消息，指出：＆＃34;无法从Undefined中读取属性0.0＆＃34;

function submit() {
  var app = SpreadsheetApp;
  var tplSheet = app.getActiveSpreadsheet().getSheetByName("POTemplate");
  var tplFRow = 22, tplLRow = tplSheet.getLastRow();
  var tplRowsNum = tplLRow - tplFRow + 1;
  var tplFCol = 1, tplLCol = 16;
  var tplColsNum = tplLCol - tplFCol + 1;
  var rangeData = tplSheet.getRange(22, 1, 5, 15).getValues();
  var colIndexes = [0, 3, 10, 12, 15];
  var fData = filterByIndexes(rangeData, colIndexes);
  var target = "POHistory";
  var targetSheet = app.getActiveSpreadsheet().getSheetByName(target);
  var tgtRow = targetSheet.getLastRow() + 1;
  var tgtRowsNum = fData.length - tgtRow + 1;
  var tgtCol = 1;
  var tgtColsNum = fData[0].length - 1 + 1;
  targetSheet.getRange(tgtRow, tgtCol, tgtRowsNum, 
  tgtColsNum).setValues(fData);
}

function filterByIndexes(twoDArr, indexArr) {
  var fData = [];
  twoDArr = twoDArr.transpose();
  for(var i = 0; i < indexArr.length; i++) {
     fData.push(twoDArr[indexArr[i]]);
  }
  return fData.transpose();
}

Array.prototype.transpose = function() {
  var a = this,
      w = a.length ? a.length : 0,
      h = a[0] instanceof Array ? a[0].length : 0;
  if (h === 0 || w === 0) {return [];}
  var i, j, t = [];
  for (i = 0; i < h; i++) {
     t[i] = [];
     for (j = 0; j < w; j++) {
       t[i][j] = a[j][i];
     }
  }
  return t;
}
