show-summary
:summary-method="getSummaries"
第二步：逻辑部分
const getSummaries = (param) => {const { columns, data } = param;const sums = [];columns.forEach((column, index) => {if (index === 0) {sums[index] = '总价';return;}const values = data.map((item) => Number(item[column.property]));if ((index >= 6 && index < 10) || (index >= 12 && index <= 34) || index == 38) {sums[index] = values.reduce((prev, curr) => {const value = Number(curr);if (!isNaN(value)) {return prev + curr;} else {return prev;}}, 0);sums[index] = sums[index].toFixed(2);// sums[index] += ' 元';} else {sums[index] = '';}});return sums;};原创作者：吴小糖
