我正在尝试对此进行调整：
https://codepen.io/adrianjacob/full/KdVLXY，使移动设备和台式设备的表头和第一行第一行都保持“粘滞”状态。
我已经在CSS中完成了此操作
thead th {
position: sticky;
top: 0;
}
和
tbody tr:first-child td {
position: sticky;
top: 50px;
background:white;
}
在需要的地方显示“粘性”，但在移动设备上没有显示“ thead”，而在移动设备和台式机上显示的是“ tr”，并且很粘。
我还需要“ thead”上方的那些色线来显示并保持粘性。 感谢您提供的任何帮助。

我将彩色线条制作为伪元素，并且还添加到ul位置：这就是所缺少的粘性;）
// DIRTY Responsive pricing table JS
$( 'ul' ).on( 'click', 'li', function() {
let pos = $(this).index()+2;
$('tr').find('td:not(:eq(0))').hide();
$('td:nth-child('+pos+')').css('display','table-cell');
$('tr').find('th:not(:eq(0))').hide();
$('li').removeClass('active');
$(this).addClass('active');
});
// Initialize the media query
let mediaQuery = window.matchMedia('(min-width: 640px)');
// Add a listen event
mediaQuery.addListener(doSomething);
// Function to do something with the media query
function doSomething(mediaQuery) {
if (mediaQuery.matches) {
$('.sep').attr('colspan',5);
} else {
$('.sep').attr('colspan',2);
}
}
// On load
doSomething(mediaQuery);/* DIRTY Responsive pricing table CSS */
