在 Y 轴上固定一个元素，但在 x 轴上滚动页面？ [复制]

【问题描述】：

是否可以将元素固定到页面上的“y”位置，但是当左右滚动时，该元素也会在 x 轴上滚动？

在我的例子中，我有一个总共有 20 列的数据表（如果不滚动页面就无法显示）。我想将表格标题固定到页面顶部，但是这也修复了 x 滚动，因此在左右滚动时，标题不会移动。是否可以只修复元素的 y 定位？

我在这里创建了一个基本的小提琴，显示一个标准表：http://jsfiddle.net/0n9d92er/。基本上，我希望标题 1-20 固定在顶部（用于垂直滚动），但是当向右滚动时，我应该能够看到从 1 到 20 的每个标题（当水平滚动时）。

标签： html css scroll


【解决方案1】：

这是一个不需要 jQuery 的快速示例，它使用 JavaScript 在页面滚动时使标题向下浮动：

var thead = document.querySelector(".tg tr:first-child");
window.onscroll = function() {
    thead.style["-webkit-transform"] = "translateY(" + window.scrollY + "px)";
    thead.style.transform = "translateY(" + window.scrollY + "px)";
};
.header {
    width: 2000px;
}
.tg  {
    border-collapse:collapse;
    border-spacing:0;
}
.tg td {
    font-family:Arial, sans-serif;
    font-size:14px;
    padding:10px 5px;
    border-style:solid;
    border-width:1px;
    overflow:hidden;
    word-break:normal;
}
.tg th {
    font-family:Arial, sans-serif;
    font-size:14px;
    font-weight:normal;
    padding:10px 5px;
    border-style:solid;
    border-width:1px;
    overflow:hidden;
    word-break:normal;
}
