1.用table的样式写，推荐用这种写比较方便

<template>
	<view>
		<h3 style="text-align: center;">用 table 样式写</h3>
		<view style="margin: 20upx;">
			<scroll-view scroll-x="true" scroll-y="true"  
				style="border: 1upx solid #eee; width: 100%;height: 400upx;" @scrolltolower="lower">
				<view class="table" :style="[{'width':tableWidth()}]">
					<!-- 表头 -->
					<!-- 固定列样式用title-cell-left 或 title-cell-right -->
					<view class="table-header">
						<view :class="item1.type" :style="[{'width':item1.width + 'upx'}]"  v-for="(item1,index1) in headerList" :key="index1">
							<view class="cell ">{{item1.title}}</view>
						</view>
					</view>
					<!-- 数据行 -->
					<view class="table-body">
						<view class="table-tr" v-for="(item2,index2) in dataList" :key="index2">
							<view :class="headerList[0].type" :style="[{'width':headerList[0].width + 'upx'}]">
								<view class="cell ">{{item2.id}}</view>
							</view>
							<view :class="headerList[1].type" :style="[{'width':headerList[1].width + 'upx'}]">
								<view class="cell " style="text-align: center;">{{item2.name}}</view>
							</view>
							<view :class="headerList[2].type" :style="[{'width':headerList[2].width + 'upx'}]">
								<view class="cell ">{{item2.address}}</view>
							</view>
						</view>
					</view>
				</view>
			</scroll-view>
		</view>
		
	</view>
</template>

<script>
	export default {
		data() {
			return {
				headerList:[

			}
		},
		created() {
			this.tableWidth()
		},
		methods: {
			//计算表格宽度
			tableWidth() {
				let width = 0;
				this.headerList.forEach(item => {
					width += item.width ;
				})
				return width + 'upx';
			},
            //滚动到底部加载下一页
            lower(){
            }
		}
	}
</script>

<style lang="scss" scoped>
	$border-color: #E4E4E4;

2.table

（1）固定列需要计算下left多少或者right多少

（2）固定列后border会变成透明，可以用css的outline（轮廓线）样式实现，outline是不占空间的

<template>
	<view>
		<h3 style="text-align: center;">	table</h3>
		<view style="margin: 20upx;">
			<scroll-view scroll-x="true" scroll-y="true"
				style="border: 1upx solid #eee; width: 100%;height: 250upx;" >
				<view class="table-y">
					<table :style="[{'width':tableWidth()}]"  >
						<thead>
							<tr  >
								<th class="table-th" 
									:style="[{'width':item3.width + 'upx',
										'left':(item3.left ? item3.left + 'upx':''),
										'z-index':(item3.left ? 80 :20)
										}]"  
									v-for="(item3,index3) in headerList1" :key="index3">
									{{item3.title}}
								</th>
							</tr>
						</thead>
						<tbody>
							<tr  v-for="(item4,index4) in dataList1" :key="index4">
								<td :style="[{'width':headerList1[0].width + 'upx',
											'left':(headerList1[0].left ? headerList1[0].left + 'upx':''),}]"
									:class="headerList1[0].left ?  'table-td-left':''">
									{{item4.id}}
								</td>
								<td :style="[{'width':headerList1[1].width + 'upx',
											'left':(headerList1[1].left ? headerList1[1].left + 'upx':''),}]"
									:class="headerList1[1].left ?  'table-td-left':''">
									{{item4.name}}
								</td>
								<td :style="[{'width':headerList1[2].width + 'upx'}]">
									{{item4.address}}
