vue a-table自定义表头颜色，以及自定义表头文字换行

又有让我掉头发的需求，看着很容易，但是也搞了好久，累了

<template><div><div v-for="(item1, index1) in totalArr" :key="index1 + 'A'" class="content-container" style="margin-top: 20px">{{ `${item1.name}` }}<div class="table-wrap"><a-tablesize="small"class="sum-table"borderedrowKey="id":columns="getColumns(item1.name)":pagination="false":dataSource="item1.data"/></div></div></template> <script>const g_sup_1 = {backgroundColor: '#e1edfe',fontWeight: 'bold',

}</script>

以上就是全部啦，
知识点：1、子项目名称可以根据父项目动态改可搜{tableName}子项目
2、自定义修改表头背景颜色，可搜customHeaderCell
3、自定义修改表头文字颜色，比如想换行或者其他，可搜 title: () => (
4、自定义合并表格 ,可搜 getInfo数据处理+ if (rowMap[projectName] && rowMap[projectName].index === index) {渲染处理

数据大概是这样的，懒的写直接截图
