所以我有一个 html 表格，我试图使表格标题在滚动时具有粘性，因为会有很多行，但它不起作用。我无法让标头粘住或保持在固定位置。我的表格有一个宽度为 250% 的固定布局。我不太确定如何在不破坏当前 CSS 的情况下使表格标题具有粘性，任何指导都会有所帮助，谢谢。

发生这种情况的原因有很多：
如果元素的任何父元素上的溢出设置为隐藏、滚动或自动，则位置粘性很可能不起作用。
如果任何父元素设置了高度，位置粘性可能无法正常工作。
display设置为
blocktable等属性之外的其他内容，位置粘性将不起作用
许多浏览器仍然不支持粘性定位。查看哪些浏览器支持position：sticky。
检查祖先元素是否设置了溢出（例如溢出：隐藏）；尝试切换它。您可能必须在 DOM 树上爬得比您预期的更高。
这可能会影响你的位置：粘在后代元素上。
简单的例子 添加类和布局应该不难。
