在使用element-ui时表单的表头在切换页面时第一次进入页面容易是白色字体解决方法

在里面添加:header-cell-style="{ color: 'black' }"

 <el-table
    :data="tableData"
    style="width: 100%"
    height="250"
   :header-cell-style="{ color: 'black' }"
></el-table>

正确代码是

<template>
  <el-table
    :data="tableData"
    style="width: 100%"
    height="250"
   :header-cell-style="{ color: 'black' }"
>
    <el-table-column
      fixed
      prop="date"
      label="日期"
      width="150">
    </el-table-column>
    <el-table-column
      prop="name"
      label="姓名"
      width="120">
    </el-table-column>
    <el-table-column
      prop="province"
      label="省份"
      width="120">
    </el-table-column>
    <el-table-column
      prop="city"
      label="市区"
      width="120">
    </el-table-column>
    <el-table-column
      prop="address"
      label="地址"
      width="300">
    </el-table-column>
    <el-table-column
      prop="zip"
      label="邮编"
      width="120">
    </el-table-column>
  </el-table>
</template>
