"刷新工作表中的单元格"

Question

我有这个脚本：

  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var sheet = ss.getSheetByName(sheetName);
  var orig = sheet.getRange(row,col).getFormula(); 
  var temp = orig.replace("=", "?");
  sheet.getRange(row,col).setFormula(temp); 
  SpreadsheetApp.flush();
  sheet.getRange(row,col).setFormula(orig); 
}
