您可以使用 HTML 服务。我自己对此了解不多，但我认为以下内容可能会满足您的需求：
在 .gs 文件的顶部：
var ss = SpreadsheetApp.getActiveSpreadsheet();
var htmlApp = HtmlService.createTemplateFromFile("html");
var status = "Loading....."
htmlApp.data = status;
ss.show(htmlApp.evaluate()
.setWidth(300)
.setHeight(200));
最后（就在最后一个大括号之前）：
var status = "Finished!"
htmlApp.data = status;
ss.show(htmlApp.evaluate()
.setWidth(300)
.setHeight(200));
在名为“html”的新 HTML 脚本文件中：
<!DOCTYPE html>
<html>
<head>
<base target="_top">
</head>
<body>
<h2>Updating..</h2>
<p id="status">(innerHTML).</p>
<div id="imageico"></div>
<script>
var imageContainer = document.getElementById("imageico");
if (<?= data ?> != "Finished!"){
document.getElementById("status").innerHTML = "Running script, please wait..";
} else {
document.getElementById("status").innerHTML = "Finished! You can now close the window.";
closeBtn();
}
function closeBtn(){
var button = document.createElement("INPUT");
button.setAttribute("type", "button");
button.setAttribute("value", "Close");
button.setAttribute("onclick", "closeWindow();");
imageContainer.appendChild(button);
}
function closeWindow(){
google.script.host.close();
}
</script>
</body>
</html>
EDITED根据评论
在您的 .gs 文件中：
function test() {
htmlApp("","");
/*
*
* Put your code in here....
*
*/
Utilities.sleep(3000); // change this value to show the "Running script, please wait.." HTML window for longer time.
htmlApp("Finished!","");
Utilities.sleep(3000); // change this value to show the "Finished! This window will close automatically. HTML window for longer time.
htmlApp("","close"); // Automatically closes the HTML window.
}
function htmlApp (status,close) {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var htmlApp = HtmlService.createTemplateFromFile("html");
htmlApp.data = status;
htmlApp.close = close;
ss.show(htmlApp.evaluate()
.setWidth(300)
.setHeight(200));
}
在名为“html”的 HTML 脚本文件中：
<!DOCTYPE html>
<html>
<head>
<base target="_top">
</head>
<body>
<h2>Updating..</h2>
<p id="status">(innerHTML).</p>
<div id="imageico"></div>
<script>
var imageContainer = document.getElementById("imageico");
if (<?= data ?> != "Finished!"){
document.getElementById("status").innerHTML = "Running script, please wait..";
} else {
document.getElementById("status").innerHTML = "Finished! This window will close automatically.";
}
if (<?= close ?> == "close"){
google.script.host.close();
}
</script>
</body>
</html>
