这个甘特图之前插件里，没有找到能固定label标签在屏幕上的办法，用css各种办法都没有实现，所以我我直接手写定位，用js监听滚动条滚动的距离，然后同步移动甘特图label标签，造成一种定位的错觉，以下是代码：

我用的是介绍 | Pure Admin 保姆级文档（已更新至最新版v6.0.0）这个前端框架，感觉功能还是非常完善的，作者全职做开源，希望大家也多多支持。

这个是全部甘特图的示例代码

<script setup lang="ts">

const scrollLeft = ref(0);
// 添加容器引用
const containerRef = ref(null);// 现有数据保持不变

重点处理方法是：

// 添加滚动位置状态
const scrollLeft = ref(0);
// 添加容器引用
const containerRef = ref(null);// 添加和移除滚动事件监听
onMounted(() => {// 延迟添加事件监听，确保DOM已完全渲染setTimeout(() => {if (containerRef.value) {containerRef.value.addEventListener("scroll", handleScroll);console.log("滚动监听已添加", containerRef.value);}}, 500);
});// 滚动事件处理函数
function handleScroll(e) {scrollLeft.value = e.target.scrollLeft;console.log("滚动事件触发", scrollLeft.value);const labels = document.querySelectorAll(".g-gantt-row-label, .g-gantt-row-label-container");labels.forEach(label => {label.style.position = "absolute";label.style.left = scrollLeft.value + "px";});
}
onUnmounted(() => {if (containerRef.value) {containerRef.value.removeEventListener("scroll", handleScroll);console.log("滚动监听已移除");}
});
