翻译一下下面这段代码option.style.position = "relative"; option.style.paddingRight = "12px"; const dot = document.createElement("span"); dot.style.display = "block"; dot.style.position = "absolute"; dot.style.content = "' '"; dot.style.width = "6px"; dot.style.height = "6px"; dot.style.borderRadius = "50%"; dot.style.backgroundColor = "blue"; dot.style.left = "calc(100% - 10px)"; dot.style.top = "50%"; dot.style.transform = "translateY(-50%)"; option.appendChild(dot);

这段代码的功能是在指定单元格元素中添加一个蓝色的圆点。以下是代码的翻译:
```
option.style.position = "relative";
// 设置单元格元素的 position 属性为 relative
option.style.paddingRight = "12px";
// 设置单元格元素的 paddingRight 属性为 12px,防止圆点被遮挡
const dot = document.createElement("span");
// 创建一个 span 元素用于显示圆点
dot.style.display = "block";
dot.style.position = "absolute";
dot.style.content = "' '";
dot.style.width = "6px";
dot.style.height = "6px";
dot.style.borderRadius = "50%";
dot.style.backgroundColor = "blue";
dot.style.left = "calc(100% - 10px)";
dot.style.top = "50%";
dot.style.transform = "translateY(-50%)";
// 设置 span 元素的样式
option.appendChild(dot);
// 将 span 元素添加到单元格元素中
```
