【element-ui】element-ui中,使用el-tabs嵌套el-table,初次加载tab页时table表头和表格数据错位
\#\#\# 问题描述
element-ui中,使用el-tabs嵌套el-table,每个tab页下放置引入的子组件。并有v-if控制它的显示。子组件中的el-table中设置了列的宽度。问题出在初次加载tab页时table表头和表格数据错位。点击其他tab页再切换回去的时候错位消失了。
下图是初次点击左侧菜单进来时的状态
点击其他tab页比如已审批以后,再切回原来的第一个tab后

回答:
我是监听数据获取之后,手动调用一下这个方法,手动触发表格视图更新
this.$refs.tableRef.doLayout();
