highcharts的甘特图设置滚动时表头固定，让其他内容跟随滚动

效果图：最左侧的分类列是跟随甘特图滚动的，因为这一列如果需要自定义，比如表格的话可能会存在行合并的情况，这个时候甘特图是没有办法做的，然后甘特图的表头又需要做滚动时固定，所以设置了甘特图滚动时，让指定元素跟随滚动
请添加图片描述

如果元素需要滚动，但是不显示滚动条的话可以设置

首先，确保目标元素具有固定的高度和宽度，并且超过该尺寸的内容会溢出。
将元素的 CSS 样式中的 overflow 属性设置为 hidden，以隐藏默认的滚动条。

<div style="overflow: hidden"></div>

highcharts监听滚动事件

const chart = Highcharts.chart('container', {chart: {...},...},...
});
chart.scrollingContainer.addEventListener('scroll', (el) => {console.log(el);
});

需要引入highcharts-gantt.js，moment.js
