移动端需要表格展示数据时，需要滑动表格实现展示更多数据的目的，固定表格的首行和首列可在查看数据时更加直观。

分解图
首先将表格分成左右两部分，左边第一列在上下滑动是header部分需要固定；右边第一行在左右滑动时firstRow和header部分也需要是固定的。可将这几个划分区域分别用table填充，滑动tableBody时保持firstRow和firstCol的同步滑动即可。
<template>
<div class="content-table">
<div class="left-div">
<div class="left-div1">
<table>
<tr>
<th>{{ header }}</th>
</tr>
</table>
</div>
<div
ref="firstColLayer"
class="left-div2"
>
<table class="left-table2">
<tr
v-for="(col, index) in firstCol"
:key="index"
>
<td>
<p>{{ col }}</p>
</td>
</tr>
</table>
</div>
</div>
<div class="right-div">
<div
ref="firstRowLayer"
class="right-div1"
>
<table class="right-table1">
<tr>
<th
v-for="(row, index) in firstRow"
:key="index"
>
{{ row }}
</th>
</tr>
</table>
</div>
<div
ref="tableContainer"
class="right-div2"
@scroll="tableScroll($event)"

<table class="right-table2">
<tr
v-for="(body,index) in tableBody"
