我重新编写了您的代码，我认为它可以完成您现在所假装的工作.在这种情况下，我不会进行纸张保护，而是分别保护所有范围:

I've reworked your code and I think it does what you pretend now. In this case, I don't make a sheet protection but protect all the ranges separately:

function Sheet_Ranges_Protection() {
  var Veranda_Test = SpreadsheetApp.openById("Sheet ID");
  var Veranda_Sheets = Veranda_Test.getSheets();

  for(var SheetNumb = 0; SheetNumb < Veranda_Sheets.length; SheetNumb++) {

    var me = Session.getEffectiveUser();

    // Define ranges that will be protected for everyone
    var range1 = Veranda_Sheets[SheetNumb].getRange(6, 1, Veranda_Sheets[SheetNumb].getMaxRows(), Veranda_Sheets[SheetNumb].getMaxColumns());
    var range2 = Veranda_Sheets[SheetNumb].getRange(1, 8, 5, Veranda_Sheets[SheetNumb].getMaxColumns());
    var range3 = Veranda_Sheets[SheetNumb].getRange(1, 4, 5);
    var ranges = [range1, range2, range3];

    // Set protection for all the sheet minus QC/PLN ranges
    for(var i = 0; i < ranges.length; i++) {
      var rangeProtection = ranges[i].protect().setDescription('Range protection');
      rangeProtection.addEditor(me);
      rangeProtection.removeEditors(rangeProtection.getEditors());
      if (rangeProtection.canDomainEdit()) {
        rangeProtection.setDomainEdit(false);
      }
    }

    var QC_Range         = Veranda_Sheets[SheetNumb].getRange("E1:G5");
    var PLN_Range        = Veranda_Sheets[SheetNumb].getRange("A1:C5");

    // Set protection for QC range
    var QC_protection = QC_Range.protect().setDescription('QC protection');
    QC_protection.removeEditors(QC_protection.getEditors());
    QC_protection.addEditor('Editor1@gmail.com');
    if (QC_protection.canDomainEdit()) {
      QC_protection.setDomainEdit(false);
    }

    // Set protection for PLN range
    var PLN_protection = PLN_Range.protect().setDescription('PLN protection');
    PLN_protection.removeEditors(PLN_protection.getEditors());
    PLN_protection.addEditor('Editor2@gmail.com');
    if (PLN_protection.canDomainEdit()) {
      PLN_protection.setDomainEdit(false);
    }    
  }
}

我希望这对您有用！
