编写函数
formatNumber
formatNumber(num){
if (num != null)
return num.toLocaleString('en-US');
},
用法
<el-table-column label="金额" align="right" prop="amount" key="amount":show-overflow-tooltip='true'><template slot-scope="scope">{{ formatNumber(scope.row.amount) }}</template></el-table-column>表格统计行
el-table 标签中加入
show-summary :summary-method="getSummaries"编写函数
getSummaries
getSummaries(param) {const {columns, data} = param;const sums = [];columns.forEach((column, index) => {if (index === 0) {sums[index] = '合计';return;}const values = data.map(item => Number(item[column.property]));if (!values.every(value => isNaN(value))) {sums[index] = values.reduce((prev, curr) => {const value = Number(curr);if (!isNaN(value)) {return Math.round((prev + value) * 100) / 100;} else {return prev;}}, 0);//sums[index] += '';// 返回结果显示千分位sums[index] = sums[index].toString().replace(/\B(?=(\d{3})+(?!\d))/g, ",");} else {sums[index] = '';}});return sums;},Leslie Lee 随笔
