是否可以在Google Apps Scripts for Google Sheets中为单个单元格创建颜色淡入淡出？

function fadeCellColor() {
  var sheet = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
  var range = sheet.getRange("A1"); // 需要渐变颜色的单元格
  var startColor = "#FFFFFF"; // 渐变起始颜色（白色）
  var endColor = "#000000"; // 渐变结束颜色（黑色）
  var duration = 3; // 渐变持续时间（秒）

  var steps = 10; // 渐变步数
  var interval = duration * 1000 / steps; // 每一步的时间间隔

  for (var i = 1; i <= steps; i++) {
    var ratio = i / steps;
    var color = blendColors(startColor, endColor, ratio);
    range.setBackground(color);
    Utilities.sleep(interval);
  }
}

// 颜色混合函数
function blendColors(color1, color2, ratio) {
  var hex = function (x) {
    x = x.toString(16);
    return (x.length === 1) ? '0' + x : x;
  };

  var r = Math.ceil(parseInt(color1.substring(1, 3), 16) * ratio + parseInt(color2.substring(1, 3), 16) * (1 - ratio));
  var g = Math.ceil(parseInt(color1.substring(3, 5), 16) * ratio + parseInt(color2.substring(3, 5), 16) * (1 - ratio));
  var b = Math.ceil(parseInt(color1.substring(5, 7), 16) * ratio + parseInt(color2.substring(5, 7), 16) * (1 - ratio));

  var blend = "#" + hex(r) + hex(g) + hex(b);
  return blend;
}
