el-tabel名称排序问题

本文主要是介绍el-tabel名称排序问题，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

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

在这里插入图片描述

倒序

在这里插入图片描述

代码如下：

<template><div class="personalFiles containerBox"><div class="personalFileCont"><el-tablev-loading="loading":data="tabelList"row-key="uuid"ref="tableRef"><el-table-column type="selection" width="55"></el-table-column><el-table-columnlabel="文件名"min-width="250"sortable:sort-method="sortName"><template slot-scope="scope"><spanclass="cursor-pointer"><img:src="getIcon(scope.row.name, scope.row.uuid, scope.row.dir)"alt=""class="tabelImg"/><spanclass="fileNameCont ellipsis":class="isCollapse ? 'detailFileName' : ''">{{ scope.row.name }}</span></span></template></el-table-column><el-table-column label="最后修改人">xxx</el-table-column><el-table-columnlabel="大小"sortableprop="size":default-sort="{ prop: 'size', order: 'descending' }"><template slot-scope="scope">{{ humanFileSize(scope.row.size) }}</template></el-table-column><el-table-columnlabel="修改时间"prop="updateTime"sortable:default-sort="{ prop: 'updateTime', order: 'descending' }"></el-table-column></el-table></div></div>
</template>
<script>
import {getMatterPage,
} from "@/api/personalFiles";
import { humanFileSize, isImage } from "@/utils/FileUtil";
import { getIcon } from "@/utils/Matter.js";
import { getChartType } from "@/utils/index";
export default {name: "spaceDetailList",props: {curSpaceObj: {type: Object,default: () => {}}},data() {return {queryParams: {page: 1,pageSize: 10,puuid: "root",deleted: false,orderDir: "DESC",orderName: "ASC",spaceUuid: '',},total: 0,loading: false,tabelList: [],};},mounted() {this.$nextTick(() => {this.queryParams.spaceUuid = this.curSpaceObj.uuidthis.getList();})},methods: {humanFileSize,getIcon,isImage,getList() {this.loading = true;getMatterPage({ ...this.queryParams }).then((res) => {this.tabelList = res.data.data;this.total = res.data.totalItems;}).finally(() => {this.loading = false;});},// 排序sortName(str1, str2) {let strName1 = str1.name;let strName2 = str2.name;let res = 0;for (let i = 0; ; i++) {if (!strName1[i] || !strName2[i]) {res = strName1.length - strName2.length;break;}// 此处判断文件类型 dir-true代表是文件夹if (str1.dir != str2.dir) {res = 1;break;}const char1 = strName1[i];const char1Type = getChartType(char1);const char2 = strName2[i];const char2Type = getChartType(char2);// 类型相同的逐个比较字符if (char1Type[0] === char2Type[0]) {if (char1 === char2) {continue;} else {if (char1Type[0] === "zh") {res = char1.localeCompare(char2);} else if (char1Type[0] === "en") {res = char1.charCodeAt(0) - char2.charCodeAt(0);} else {res = char1 - char2;}break;}} else {// 类型不同的，直接用返回的数字相减res = char1Type[1] - char2Type[1];break;}}return res;},},
};
</script>
<style lang="scss" scoped>
@import url('@/assets/styles/personalFiles.scss');
</style>

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];
}
