el-table魔改样式出现BUG，表格内容区域出现滚动条

问题：el-table表格内容区域在高度自适应的情况下冒出滚动条

解决办法：

代码排查后发现时我设置了fixed:"xxx" 属性就会导致滚动条出现的问题，不设置则无。

javascript 复制代码

[
  { type: 'index', label: '序号', fixed: 'left' },
  { prop: 'enterprisesName', label: '企业名称' },
  { prop: 'orderAmount', label: '销售金额', format: 'price' }
]
<el-table-column fixed="left" label="序号">
</el-table-column>

设置fixed:"xxx" 后elementui就会多渲染几个css。重点看bottom:-1px，这是官方设置的值。我发现重置为bottom:-0px，问题就能解决了，下面直接贴解决代码。
把样式放在全局CSS中

css 复制代码

.el-table__body-wrapper tr td.el-table-fixed-column--left.is-first-column::before,
.el-table__body-wrapper tr td.el-table-fixed-column--left.is-last-column::before,
