layui-vue怎么修改table表头

看下效果

直接上代码

<template>
  <lay-table :default-toolbar="true" :columns="columns5" :data-source="dataSource5">
    <template #title="{column}">
      <span class="text-center">{{column.title}}</span>
      <lay-tooltip content="我是这个地址的注释" position="top">
            <lay-icon type="layui-icon-tips" size="15px" style="cursor: pointer;"></lay-icon>
       </lay-tooltip>
    </template>
  </lay-table>
</template>

<style>
/* 使用 has 来选择父元素 */
span:has(.text-center) {
  width: 100%;
  display: block;
  text-align: center;
}
</style>

<script>
