elementPlus中的tabs中的头部点击后面的标题然后,往后滚动

	nextTick(() => {
		const header = tabsRef.value.$el.querySelector('.el-tabs__nav-scroll');
		if (!header) return;
		const tabWidth = 200;
		const tabIndex = tab.index;
		const targetOffset = tabIndex * tabWidth;
		const headerWidth = header.clientWidth;
		const scrollLeft = header.scrollLeft;
		let newScrollLeft = targetOffset;
		if (targetOffset > (headerWidth/4)*3) {
			newScrollLeft = headerWidth/2;
		}	else if (targetOffset < (headerWidth/4)*3) {
			newScrollLeft = -targetOffset;
		}
		header.scrollLeft = newScrollLeft;
	});

最好将tabs自带的箭头隐藏掉,有冲突

::v-deep .el-tabs__nav-next,::v-deep .el-tabs__nav-prev {
	display: none!important;
}
