// 格式化金钱
const digitsRE = /(d{3})(?=d)/g
export function currency(value, currency, decimals) {
    value = parseFloat(value)
    if (!isFinite(value) || (!value && value !== 0)) return ‘‘
    currency = currency != null ? currency : ‘￥‘
    decimals = decimals != null ? decimals : 2
    var stringified = Math.abs(value).toFixed(decimals)
    var _int = decimals
        ? stringified.slice(0, -1 - decimals)
        : stringified
    var i = _int.length % 3
    var head = i > 0
        ? (_int.slice(0, i) + (_int.length > 3 ? ‘,‘ : ‘‘))
        : ‘‘
    var _float = decimals
        ? stringified.slice(-1 - decimals)
        : ‘‘
    var sign = value < 0 ? ‘-‘ : ‘‘
    return sign + currency + head +
        _int.slice(i).replace(digitsRE, ‘$1,‘) +
        _float
}

效果：

 

 使用过滤器，使用如下:

main.js导入：
import { currency } from ‘./common/currency.js‘
Vue.filter("currency", currency);


//表格使用
             <el-table-column
                    prop="moneyGood"
                    label="金额（元）"
                    min-width="50"
                    sortable
                    align="center"
                  >
                    <template slot-scope="scope">
                      <span>{{scope.row.money| currency(‘￥‘)}}</span>
                    </template>
                  </el-table-column>


//文本使用
 <p class="cc">{{moneyGood| currency(‘￥‘)}}</p>
