1. 确认浏览器版本支持
const cssSupport = (attr: any, value: string) => { const element = document.createElement('div') if (attr in element.style) { element.style[attr] = value return element.style[attr] === value } else { return false } } cssSupport ('position', 'sticky')
2. 确认父亲元素以及自身没有用overflow:hidden

3. table 中如果要 thead 用 position：sticky ，这个style 要加到 th上，而不是thead
