js content Use jq's on event to monitor scrolling and modify my own style according to the style of my own project. Everyone can adjust it themselves.

var tableCont = $('.section-scroll tr th'); //获取th var tableCont_child = $('.section-scroll tr th div'); //获取th下边的div var tableScroll = $('.section-scroll'); //获取滚动条同级的class function scrollHandle() { var scrollTop = tableScroll.scrollTop(); // 当滚动距离大于0时设置top及相应的样式 if (scrollTop > 0) { tableCont.css({ "top": scrollTop + 'px', "marginTop": "-1px", "padding": 0 }); tableCont_child.css({ "borderTop": "1px solid gainsboro", "borderBottom": "1px solid gainsboro", "marginTop": "-1px", "padding": "8px" }) } else { // 当滚动距离小于0时设置top及相应的样式 tableCont.css({ "top": scrollTop + 'px', "marginTop": "0", }); tableCont_child.css({ "border": "none", "marginTop": 0, "marginBottom": 0, }) } } tableScroll.on('scroll', scrollHandle);

In this way, the first method of fixing the header is completed. It looks basically flawless on the browser, but when I use mui to use this method, it may be that the scrolling of the app has rebound, so the effect will appear a bit laggy. I'm a noob, don't comment if you don't like it (reply welcome...).

2. Use the jq plug-in (this is the jq plug-in that I asked to do the header last year in the company. Due to technical issues, I used jq in angular. Anyway, it was solved in the end haha)

Because I made a simple and hasty demo last year. I took a screenshot and mainly used the jquery.fixedheadertable.min.js plug-in. The demo in the picture above (don’t comment if you don’t like it, I’m a novice)
