el-tabel名称排序问题

el-tabel排序

最终实现功能如下：

排序限制为：
文件夹>普通文件
数字（0->9）->大写字母（A->Z）->小写字母（a->z）->中文拼音（a->z）

正序

倒序

代码如下：

<template>
  <div class="personalFiles containerBox">
    <div class="personalFileCont">
      <el-table
        v-loading="loading"
        :data="tabelList"
        row-key="uuid"
        ref="tableRef"
      >
        <el-table-column type="selection" width="55"></el-table-column>
        <el-table-column
          label="文件名"
          min-width="250"
          sortable
          :sort-method="sortName"
        >
          <template slot-scope="scope">

排序使用到的getChartType方法,代码中用到图片和字节转换方法跟当前功能无关就不展示了

// 排序
export function getChartType(char) {
  // 数字（0->9）->大写字母（A->Z）->小写字母（a->z）->中文拼音（a->z）
  if (/^[\u4e00-\u9fa5]$/.test(char)) {
    return ["zh", 300];
  }
  if (/^[a-zA-Z]$/.test(char)) {
    return ["en", 200];
  }
  if (/^[0-9]$/.test(char)) {
    return ["number", 100];
  }
  return ["others", 999];
}
