element table合计定制化
el-table 中加入 show-summary :summary-method=“getSummaries”
<el-table :data='tableData' show-summary :summary-method="getSummaries" border style='width: 100%' max-height="271px" v-loading='tableLoading' show-overflow-tooltip></el-table >
方法
getSummaries(param) { //统计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]));let arrName = ['accountNo','name'] //表格中不统计的字段if ( !arrName.includes(column.property) ) {if (!values.every(value => isNaN(value))) {let data = values.reduce((prev, curr) => {const value = Number(curr);if (!isNaN(value)) {return prev + curr ;} else {return prev ;}}, 0);sums[index] = parseFloat(data).toFixed(2);//数据保留两位} else {sums[index] = '--';}}else {sums[index] = '--';}});return sums;
},
