I have a table
我有一张桌子
I can already get the id of tr (blue box in the picture)
我已经可以获得tr的id（图片中的蓝色框）
I want to add display:none to the style of tag <i> through the id (red box in the picture)
我想通过id在标签＜I＞的样式中添加display:none（图片中的红色框）
This is my idea, I wonder if it can be done?
这是我的主意，我想知道能不能做到？
Or how should I accomplish it?
或者我应该如何完成它？
tr may have 0 or more, so id may also have 0 or more
tr可能有0个或更多，因此id也可能有0或更多
Thanks

@CodeThing They are like blue and red boxes. The difference is that the id of tr is different and some of the values inside are different.
@CodeThing它们就像蓝色和红色的盒子。不同之处在于tr的id不同，并且一些值内部是不同的。
If you've got the <tr> ID and want to target the first <i> element within the 2nd <td>, you can use a fairly simple query selector
如果您有ID，并且希望以第二个中的第一个元素为目标，那么可以使用一个相当简单的查询选择器
