解釋：
根據你的問題，我理解了以下步驟：
檢查E列中是否至少有兩個獨特的主題。一種方法是找到唯一的主題列表。如果該列表的長度是或更多，則意味著您有不同的主題。在這種情況下，語句的第一個塊的計算結果為，并且您在更改主題之前的行中添加了一條黃線。2iftrue
如果您只有一個主題，即唯一主題列表的長度，則語句1的第一個塊if將評估為false。在這種情況下，腳本將檢查A列是否有2一個或多個唯一日期。如果是，if將執行語句的第二個塊，腳本將在日期更改前的行中添加一條黃線。否則，它不會做任何事情。
解決方案：
color()您可以作為獨立腳本執行。我建議您將此函數保存在一個新.gs文件中，然后在您當前的腳本中簡單地調用它。即，在您提供的代碼片段中放置您想要的color() 任何位置。
function color() {
const sss = SpreadsheetApp.getActiveSpreadsheet();
const sheet = sss.getSheetByName("TempDataSet");
const subs = sheet.getRange('E2:E'+sheet.getLastRow()).getValues().flat();
const usubs = subs.filter((value, index, self)=>self.indexOf(value) === index);
const dts = sheet.getRange('A2:A'+sheet.getLastRow()).getDisplayValues().flat();
const udts = dts.filter((value, index, self)=>self.indexOf(value) === index);
if(usubs.length>1){
subs.forEach((s,i)=>{
if(i>1){
if(subs[i]!=subs[i-1]){
sheet.getRange(i+1,1,1,5).setBackground('yellow');
}}});
}
else if (udts.length>1){
dts.forEach((d,i)=>{
if(i>1){
if(dts[i]!=dts[i-1]){
sheet.getRange(i+1,1,1,5).setBackground('yellow');
}}});
}
}
完整的解決方案：

var ssID = sss.getId();
var sheetName = sss.getName();
var sheet = sss.getSheetByName("TempDataSet");
var sheet1 = sss.insertSheet('TempDataSet_temp');
sheet.getDataRange().copyTo(sheet1.getActiveRange(), SpreadsheetApp.CopyPasteType.PASTE_VALUES, false);
sheet.getDataRange().copyTo(sheet1.getActiveRange(), SpreadsheetApp.CopyPasteType.PASTE_FORMAT, false);
var shID = sheet1.getSheetId().toString();
sheet1.getRange(2, 1, sheet.getLastRow() -1, sheet.getLastColumn()).sort({column: 1, ascending: true});
var columns_delete = [7,2]; //[7,5,4,2];
columns_delete.forEach(col=>sheet1.deleteColumn(col));
