我遇到了一个问题，我不知道最好的解释方法是什么。
我正在使用HTML 5创建一个动态表。作为它的动态，我正在形成一个循环，用于根据数据创建tr和td。
正在为一周中的每一天创建td。用户可以选择他想要查看的那一天，从而根据所选择的日期显示td。
我已经为tbody实现了滚动，因此使得thead和tbody都有'display：block'。因此，我给标题赋予了固定的宽度，现在我必须给列赋予固定的宽度以对齐它们。
现在，当我将宽度值赋给td时，我必须保留td宽度值之一，以便可以在td的其余部分强制执行宽度。因此，这个未分配的td具有太多的宽度。 如果我将宽度td全部放入，那么它们中没有一个具有我指定的宽度，整个表格不同步。
我将我的HTMl放在最后作为标题在循环中生成td的位置。如您所见，没有宽度分配给循环中的一个td。我正在使用bootstrap for css。请让我知道我在这段代码中做错了什么。很抱歉粘贴所有代码，因为我不认为我可以在小提琴中重现这个问题。

jsfiddle用于渲染代码，没有宽度到一个td：jsfiddle.net/9psjobhc
答案 0 :(得分：0)
我找到了解决问题的方法。我只是循环了几天，并在循环的最后一天插入空白td。因此，td所需的空间在末尾分配，同步保持为需要。
