Vue element el-table-column中对日期进行格式化方式(全局过滤器)

npm install vue-moment --save

import moment from 'moment'
 
Vue.use(require('vue-moment'));
Vue.prototype.moment = moment

Vue.filter('dateYMDHMSFormat',function(dateStr,pattern='YYYY-MM-DD HH:mm:ss'){
  return moment(dateStr).format(pattern);
})

<p>{{date | dateYMDHMSFormat}}</p>

<el-table-column prop="date" label="时间"></el-table-column>

<el-table-column prop="date" label="时间">
    <template slot-scope="scope">{{scope.row.date| dateYMDHMSFormat}}</template>
</el-table-column>

<el-table-column prop="cyxb" label="性别">
    <template slot-scope="scope">
        <span v-if="scope.row.cyxb == 0">男</span>
        <span v-if="scope.row.cyxb == 1">女</span>
    </template>
</el-table-column>

 <el-table-column prop="xb1" label="成员性别1"  width="120" :formatter="Formatter">


Formatter(row, column){
    if(row.xb == 0){
        return "男"
    }else if(row.xb == 1){
        return "女"
    }
}

<el-table-column
    v-for="column in cbdksTableColumns"
    :prop="column.field"
    :label="column.label"
    sortable="custom"
    :key="column.field"
    min-width="200"
>
   <template slot-scope="scope">
        <div v-if="column.field == 'cyxb'">
            <span v-html="xbFormatter(scope.row.cyxb, scope.column.property)"></span>
        //将表格数据格式化后，再用 template + v-html 展示出来
        </div>
       //<div v-else-if="column.field == 'qqfs'">中间还可以加好多判断，从此针对某列的值进行格式化。
       <div v-else>
           {{ scope.row[scope.column.property] }}//千万不要忘啦！！！
       </div>
   </template>
</el-table-column>


//之前的代码取数据比较复杂，简化代码，便于理解。
xbFormatter(value, row) {
    //性别
    let cyxbvalue = value;
    if (cyxbvalue == null || cyxbvalue == "" || cyxbvalue == undefined) {
        return cyxbvalue;
     } else {
        let dycyxb = this.xbOptions.filter((item) => item.value === cyxbvalue);//filter过滤方法（看自己的情况、需求）
        return dycyxb[0].label;//rerun的内容即为要在表格中显示的内容
    }
},

this.xbOptions.push({ label: mj.mjmc, value: mj.mjz });
