基于其他工作表值的一张工作表中的动态列 - Google表格

Question

在Google SpreadSheet中，Sheet1有3个值。 [持续时间由= DATEDIF（StartDate，EndDate，＆＃34; M＆＃34;）计算]

Sheet2有2个预定义列（Col1，Col2）和需要根据持续时间值追加的动态列。

Example 1: 
StartDate = 01-Sep-2016 and EndDate = 30-Nov-2016 
So the Duration is 2

Example 2: 
StartDate = 01-Sep-2016 and EndDate = 31-Dec-2016 
So the Duration is 3

由于列是动态的，是否可以根据列和行索引设置Columns值，而不是像下面的代码那样硬编码。

function onOpen() {
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var s1= ss.getSheetByName("Sheet1");
  var s2= ss.getSheetByName("Sheet2");
  var sDate = s1.getRange("B5").getValue();
  var sDuration = s1.getRange("B7").getValue();
  var sMonth = Utilities.formatDate(sDate, Session.getScriptTimeZone(), "MMM");
  var sYear = Utilities.formatDate(sDate, Session.getScriptTimeZone(), "YYYY");
  for (var cell = 1; cell <= sDuration; cell++) { 
      s2.getRange("C1").setValue(sMonth + ", " + sYear);
  }
}

感谢。

您找到了80％的解决方案，我只是对您的代码添加了一些更正，以使其动态运行：

function myFunction(){

  onOpen();
}

function onOpen() {
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var s1= ss.getSheetByName("Sheet1");
  var s2= ss.getSheetByName("Sheet2");
  var sDate = new Date(s1.getRange("B1").getValue()); // changed to B1 - the start date value, and sDate must be a Date Object, not string.
  var sDuration = s1.getRange("B3").getValue(); // changed to B3 - the duration value
  for (var cell = 0; cell < sDuration; cell++) {  // cell starts from 0
    var sMonth = Utilities.formatDate(sDate, Session.getScriptTimeZone(), "MMM"); // I moved this into FOR loop
    var sYear = Utilities.formatDate(sDate, Session.getScriptTimeZone(), "YYYY"); // I moved this into FOR loop
    s2.getRange(1,cell+3).setValue(sMonth + ", " + sYear); // geting range with row & column value, not with Column name
    sDate.setMonth(sDate.getMonth()+1); // add one month to sDate
  }
}

我对更改的代码有评论。我希望你觉得这很有帮助。

稍微修改了Change value of cell in same row with google script if column has certain value中的代码，它可以正常工作。

修改onOpen（）是，

function onOpen() {
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var s1= ss.getSheetByName("Sheet1");
  var s2= ss.getSheetByName("Sheet2");
  var sDate = s1.getRange("B5").getValue();
  var sDuration = s1.getRange("B7").getValue();
  var lastColumn = s2.getLastColumn();
  for (var cell = 3; cell <= lastColumn + sDuration; cell++){
    var currentCell = s2.getRange(1, cell);
    currentCell.setValue(Utilities.formatDate(sDate, Session.getScriptTimeZone(), "MMM") + ", " 
                    + Utilities.formatDate(sDate, Session.getScriptTimeZone(), "YYYY"));
    sDate.setMonth((sDate.getMonth() + 1) % 12);
  }
}
