HTML / CSS表格对齐标题和单元格

Question

我在模式中创建了一个响应表，使用insertCell通过javascript填充内容/单元格。标题是固定的，身体向下滚动。表格和模态根据屏幕高度和宽度进行调整。

但是，我无法让thead和tbody单元格在桌子内相互对齐，我不知道还有什么可以尝试，我错过了属性或什么？我试图将tr和td单元设置为相同的宽度，但没有运气。

这是一个问题的图片（显示红色圆圈，可能需要放大？）：表格单元格的图片不对齐：

.modal-full {
    min-width: calc(100vw - 380px);
    width: calc(100vw - 380px);
    min-height: 80%;
    margin: 0;
    top: 3%;
    left: 10%;
}

.modal-content {
    height: calc(100vh - 120px);
    overflow: hidden;
    background-color: #EFEFEF;
}

.modal-dialog-center {
    margin-top: 3%;
}

.modal-backdrop {
    background-color: darkgrey;
}

.modal-body {
    background-color: #EFEFEF;
}

.modal-header {
    background-color: #EFEFEF;
}

.modal-footer {
    background-color: #edf1f5;
}

.tbody2 {
    overflow-y: scroll;
    height: calc(100vh - 280px);
    position: absolute;
}

.tbody2 tr td {
    width: calc(100vw - 5px);
}

.thead2 tr th {
    width: calc(100vw - 5px);
}

.thead2 tr th:first-child {
   width: 140px;
   min-width: 140px;
}

.tbody2 tr td:first-child {
    width: 140px;
    min-width: 140px;
}

我解决了这个问题，在我的javascript代码中我设置了每个头文本的innerHTML。该文本使标题单元格大小不同。
